soc/mediatek/mt8188: Reduce lastbus configuration size by 1280 bytes

Original lastbus configuration consumes constant memory size by
allocating 16 and 8 members arrays and the utilization is bad. Refactor
the lastbus structs to save memory usage.

BRANCH=none
BUG=none
TEST=bootblock.raw.bin size is reduced from 60328 bytes to 59048 bytes.
