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.
