ARM: mach-shmobile: sh73a0 GPIO pullup improvement
On SH-Mobile, Pull UP/Downs can be controlled independently
from Function selectors (by lower nibble of PFCR).
It means people may want to use GPIO_FN_xxx_PU/PD in addition
to GPIO_IN_PU/PD which is currently supported.
This patch adds pull-up version for some input signals on
KEYSC, MMC, FSIA as well as SDHI1.
