No matter how we build the individual pinctrl drivers we will always

we gain anything from being able to compile PINCTRL as a module.
I discussed this matter with Christian on IRC and I believe we could
basically do "select PINCTRL" on ARCH_MULTIPLATFORM as the
vast majority of multiplatforms appear to be using this anyway, this
would make the submenu for pin control pop up in menuconfig
for this, and make it possible to move different subdrivers to modules
if desired.
MULTIPLATFORM does not seem to be about saving footprint bytes
on a very fine-granular level anyway, more about doing the module
loading/unloading approach to footprint.
Let's review the list of platforms that don't select PINCTRL. There
are some platforms that are indeed sensitive about memory footprint,
and I promised people that converting to multiplatform won't cause
a significant increase in kernel binary size as long as no other
platforms are enabled.

Ok, for this driver, I'll just select PINCTRL under the ARCH_BCM_MOBILE.
We can move this to ARCH_MULTIPLATFORM once we're sure this is okay
for other platforms.
