In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. Several fixups in the same code make it hard
to maintain, so move all fixups to each SoC's callback and make
meson_pinctrl_parse_dt just do the reg parsing, separate these two
parts.Overview of all current Meson SoCs fixup is as below:
+------+--------------------------------------+--------------------------+
| | | |
| SoC | EE domain | AO domain |
+------+--------------------------------------+--------------------------+
|m8 | parse regs: | parse regs: |
|m8b | gpio,mux,pull,pull-enable(skip ds) | gpio,mux,pull(skip ds)|
|gxl | fixup: | fixup: |
|gxbb | no | pull-enable = pull; |
|axg | | |
+------+--------------------------------------+--------------------------+
|g12a | parse regs: | parse regs: |
|sm1 | gpio,mux,pull,pull-enable,ds | gpio,mux,ds |
| | fixup: | fixup: |
| | no | pull = gpio; |
| | | pull-enable = gpio; |
+------+--------------------------------------+--------------------------+
|a1 or | parse regs: |
|later | gpio/mux (without ao domain) |
|SoCs | fixup: |
| | pull = gpio; pull-enable = gpio; ds = gpio; |
+------+-----------------------------------------------------------------+
Since m8-axg share the same ao fixup, make a common function
meson8_aobus_parse_dt_extra to do the job.

This change prepare the introduction of new meson SoC. This new SoC will
share the same gpio/pinconf registers but the pinmux part will be
different. While the format of the data associated with each pinmux group
will change, the way to handle pinmuxing will be similar.
To deal with this new situation, the meson_pmx_struture is kept but the
data associated to it is now generic. This allows to reuse the basic
functions which would otherwise be copy/pasted in each pinmux driver
(such as getting the name a count of groups and functions) Only the
functions actually using this specific data is taken out of the common
code and is handling the SoC pinmuxing

When meson pinctrl is enabled, all meson platforms pinctrl drivers are
built in the kernel, with a significant amount of data.
This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.
This change makes 4 pinctrl drivers (1 per SoC) out the original single
driver, allowing to compile and ship only the ones required.

Merge tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.12 cycle.
The extra week before the merge window actually resulted in some of
the type of fixes that usually arrive after the merge window already
starting to trickle in from eager developers using -next, I'm
impressed.
I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
with the onset of Samsung patches. It works great.
Apart from that it is a boring round, just incremental updates and
fixes all over the place, no serious core changes or anything exciting
like that. The most pleasing to see is Julia Cartwrights work to audit
the irqchip-providing drivers for realtime locking compliance. It's
one of those "I should really get around to looking into that" things
that have been on my TODO list since forever.

Core changes:

The GXBB and GXL/GXM pinctrl drivers had a configuration which conflicts
with uart_ao_a. According to the GXBB ("S905") datasheet the AO UART
functions are:
- GPIOAO_0: Func1 = UART_TX_AO_A (bit 12), Func2 = UART_TX_AO_B (bit 26)
- GPIOAO_1: Func1 = UART_RX_AO_A (bit 11), Func2 = UART_RX_AO_B (bit 25)
- GPIOAO_4: Func2 = UART_TX_AO_B (bit 24)
- GPIOAO_5: Func2 = UART_RX_AO_B (bit 25)
The existing definition for uart_AO_A already uses GPIOAO_0 and GPIOAO_1.
The old definition of uart_AO_B however was broken, as it used GPIOAO_0
for TX (which would be fine) and two pins (GPIOAO_1 and GPIOAO_5) for RX
(which does not make any sense).
This fixes the uart_AO_B configuration by moving it to GPIOAO_4 and
GPIOAO_5 (it would be possible to use GPIOAO_0 and GPIOAO_1 in theory,
but all existing hardware uses uart_AO_A there).
The fix for GXBB and GXL/GXM is identical since it seems that these
specific pins are identical on both SoC variants.

The driver originally supported more domains (register ranges) per
pinctrl device, but since commit 9dab1868ec ("pinctrl: amlogic: Make
driver independent from two-domain configuration") each device gets
assigned a single domain and we instantiate multiple pinctrl devices
in the DT.
Therefore, now the 'meson_domain' and 'meson_domain_data' structures
don't have any reason to exist and can be removed to make the model
simpler to understand. This commit doesn't change behavior.
