Make use of PINCTRL_GROUP_DESC() instead of open coding it.

This patch landed in linux-next as commit 1949e4630c3b ("pinctrl: 
mediatek: Make use of PINCTRL_GROUP_DESC()"). Unfortunately it causes a 
build break of ARM64 arch with standard defconfig.

PINCTRL_GROUP_DESC() macro from drivers/pinctrl/core.h contains a cast 
to (struct group_desc), what breaks users of the above macros.

Not only arm64, but also arm32. Defconfigs, so something completely
standard. This wasn't compiled which is quite surprising because cross
building defconfigs is trivial, not even mentioning testing your trees
with LKP. :(

There is no cast (*).
Thanks for report, I will check.

But this was v4 of the series and LKP actually sent a positive feedback.
Besides that I have tested this locally with modules enabled.

*) It's a compound literal, _not_ a cast.
   Taking above into consideration I'm wondering what compilers
   are in use?

In my case: standard provided by Ubuntu 22.04, so: gcc version 11.4.0
(Ubuntu 11.4.0-1ubuntu1~22.04)

kisskb reported the following m68k failures to me:
    linux-next/m68k-allmodconfig/m68k-gcc8
    linux-next/m68k-allmodconfig/m68k-gcc11
    linux-next/m68k-allmodconfig/m68k-gcc12

However, according to [1], linux-next/m68k-allmodconfig/m68k-gcc13
did succeed, so I guess you are using gcc13?

This was from my local machine. The ones used on the server are
mentioned in one of the steps:

Time to install and try an older version ;-)

Yeah, compound literals seems the often-to-break topic (as per GCC bugzilla).
Tried with GCC 8 for ARM64 and indeed it doesn't build it well.
