drivers/gpio/gpio-msm-v1.c please.  I'm now enforcing a gpio-*.c naming
convention in this directory.  The other drivers will be renamed soon.

The kconfig entries are pseudo-alphabetically sorted.  This entry
should be higher in the list.

What is the purpose of this header?  Does anything else include it?
If not, then it should be squashed into the .c file.
