nereid: adjust stack and buffer sizes for AP power-on
Powering on the AP requires more stack for a number of tasks, so this
adjusts assorted stacks that became near-full (or overflowed) and frees
up some memory by shrinking other things.
BUG=b:223044986,b:201000950
TEST=Nereid AP power control runs, stacks do not overflow
BRANCH=none
