wahoo: improve boot time and pull in bootanim display time

1) separate fstab mount
2) launch bootanim early
3) boottime cpuset/io tune
4) parallel slow init operations: write sysfs and insmod

After CL:
Boot time saved 330ms, bootanim triggered early before data/ mounted

Bug: 36780513
Test: walleye boots
