Reduce the sizes of the rcar_sysc_area and rcar_gen4_sysc_area
structures:
- parent is in the range [-1..32] or [-1..64], so s8 is sufficient,
- flags needs just 3 bits (for now), so u8 is plenty.
This reduces kernel size by:
- 288 bytes for an R-Car Gen1+Gen2 kernel (arm32),
- 1772 bytes for an R-Car Gen3+Gen4 kernel (arm64).
