msm: board-8930: Expand GPIO address space to allow for PM8917

PMIC PM8917 has more GPIOs and MPPs than PM8038.  Since the
Linux GPIO address space is determined at compile time for
MSM8930, empty mappings must be added to allow for the
additional PM8917 GPIOs and MPPs.  Modify the PM8038 GPIO and MPP
mapping macros to provide the space needed for PM8917 GPIOs and
MPPs.
