ARM: shmobile: R-Car: Shrink rcar_sysc_ch size
Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or
int is overkill:
- chan_offs contains a register offset relative to a base value
(< 512),
- chan_bit and isr_bit contain bit indices (0-31).
This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words
to 1 32-bit word.
