In the original code, some function names begin with "ingenic_gpio_",
and some with "gpio_ingenic_". For the sake of uniform style,
all of them are changed to the beginning of "ingenic_gpio_".

Add mmc2 for JZ4770 and JZ4780:
According to the datasheet, both JZ4770 and JZ4780 have mmc2. But this
part of the original code is missing. It is worth noting that JZ4770's
mmc2 supports 8bit mode while JZ4780's does not, so we added the
corresponding code for both models.
Add nemc-wait for JZ4770 and JZ4780:
Both JZ4770 and JZ4780 have a nemc-wait pin. But this part of the
original code is missing.
Add mac for JZ4770:
JZ4770 have a mac. But this part of the original code is missing.

Delete uart4 and i2c3/4 from JZ4770:
According to the datasheet, only JZ4780 have uart4 and i2c3/4. So we
remove it from the JZ4770 code and add a section corresponding the JZ4780.
Fix bugs in i2c0/1:
The pin number was wrong in the original code.
Fix bugs in uart2:
JZ4770 and JZ4780 have different uart2 pins. So the original section JZ4770
has been modified and the corresponding section of JZ4780 has been added.
Fix bugs in mmc0:
JZ4770 and JZ4780 assigned different pins to mmc0's 4~7 data lines. So the
original section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in mmc1:
JZ4770's mmc1 has 8bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in nemc:
JZ4770's nemc has 16bit mode, while JZ4780 doesn't. So the original section
JZ4770 has been modified and the corresponding section of JZ4780 has been
added. And add missing cs2~5 groups for JZ4770 and JZ4780.
Fix bugs in cim:
JZ4770's cim has 12bit mode, while JZ4780 doesn't. So the original
section JZ4770 has been modified and the corresponding section of
JZ4780 has been added.
Fix bugs in lcd:
Both JZ4770 and JZ4780 lcd should be 24bit instead of 32bit.

Merge tag 'v4.19-rc6' into devel
This is the 4.19-rc6 release
I needed to merge this in because of extensive conflicts in
the MSM and Intel pin control drivers. I know how to resolve
them, so let's do it like this.
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
Commit a203728ac6 ("pinctrl: core: Return selector to the pinctrl
driver") and commit f913cfce4e ("pinctrl: pinmux: Return selector to
the pinctrl driver") modified the return values of
pinctrl_generic_add_group() and pinmux_generic_add_function()
respectively, but did so without updating their callers. This broke the
pinctrl-ingenic driver, which treats non-zero return values from these
functions as errors & fails to probe. For example on a MIPS Ci20:
pinctrl-ingenic 10010000.pin-controller: Failed to register group uart0-hwflow
pinctrl-ingenic: probe of 10010000.pin-controller failed with error 1
Without the pinctrl driver probed, other drivers go on to fail to probe
too & the system is unusable.
Fix this by modifying the error checks to treat only negative values as
errors, matching the commits that introduced the breakage & similar
changes made to other drivers.

Merge the code of the gpio-ingenic driver into the pinctrl-ingenic
driver.
The reason behind this, is that the same hardware block handles both pin
config / muxing and GPIO.
ingenic_gpio_probe() have been marked as __init, but for the most part,
the code is the exact same as what it was in the gpio-ingenic driver.
