Add offset & mask fields to struct powerdomain
In case of AM33xx family of devices, there is no consistency between
PWRSTCTRL & PWRSTST register offsers in PRM space, for example -
PRM_XXX PWRSTCTRL PWRSTST
=======================================
PRM_PER_MOD: 0x0C, 0x08
PRM_WKUP_MOD: 0x04, 0x08
PRM_MPU_MOD: 0x00, 0x04
PRM_DEVICE_MOD: NA, NA
And also, there is no consistency between bit-offsets inside
PWRSTCTRL & PWRSTST register, for example -
PRM_XXX LOGICRET MEMON MEMRET
=======================================
GFX_PWRCTRL: 2, 17, 6
PER_PWRCTRL: 3, 25, 29
MPU_PWRCTRL: 2, 18, 22
WKUP_PWRCTRL: 3, NA, NA
This means, we need to maintain and pass on all this information
in powerdomain handle; so adding fields for,
- PWRSTCTRL/ST register offset
- Logic retention state mask
- mem_on/ret/pwrst/retst mask
Currently, this fields is only applicable and used for AM33XX devices.
