soc/amd/picasso: Up stack size to 40k for vboot hash buffer
Increasing the vboot hash buffer size greatly speeds up the SHA
calculations. Going from a standard 4k buffer to a 36k buffer
takes ~150ms of the boot and resume time.
TEST=Build & boot see that boot time has decreased.
BRANCH=Zork
BUG=b:169217270 - Zork: SHA calculation in vboot takes too long
