After commit 34e61801a3 "pinctrl: meson-gxbb: Add missing GPIODV_18
pin entry" I started to get the following warning:
"meson-pinctrl c8834000.periphs:pinctrl@4b0: names 119 do not match

It turned out that not the mentioned commit has a problem, it just
revealed another problem which had existed before.
There is no PIN GPIOX_22 on Meson GXBB.

With "SPI_MASTER=y && I2C=m", we can build mcp23s08 as a built-in driver,

To avoid the problem, this adds another dependency on I2C that enforces

On the some rockchip SOCS, some things like rk3399 specific uart2 can use
multiple pins. Somewhere between the pin io-cells and the uart it seems
to have some sort of switch to decide to which pin to actually route the
data.
+-------+ +--------+ /- GPIO4_B0 (pinmux 2)
| uart2 | -- | switch | --- GPIO4_C0 (pinmux 2)
+-------+ +--------+ \- GPIO4_C3 (pinmux 2)
(switch selects one of the 3 pins base on the GRF_SOC_CON7[BIT0, BIT1])
The routing switch is determined by one pin of a specific group to be set
to its special pinmux function. If the pinmux setting is wrong for that
pin the ip block won't work correctly anyway.

Fixups here tend to be more of a conglomerate of some of the other
repeated/systematic ones we've seen in the earlier pinctrl cleanups.
We remove module.h from code that isn't doing anything modular at
all; if they have __init sections, then replace it with init.h
One driver has a .remove that would be dispatched on module_exit,
and as that code is essentially orphaned, so we remove it. In case
anyone was previously doing the (pointless) unbind to get to that
function, we disable unbind for this one driver as well.
A couple bool drivers (hence non-modular) are converted over to
to builtin_platform_driver().
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only. All
drivers get similar changes, so they are handled in batch.
We remove module.h from code that isn't doing anything modular at
all; if they have __init sections, then replace it with init.h.
