soc/amd/picasso: Set vboot hashing block size to 36k

On picasso's psp_verstage, the vboot hash is being calculated by
hardware using relatively expensive system calls.  By increasing the
block size, we can save roughly 150ms of boot and S3 resume time.

TEST=Build & boot see that boot time has decreased.
BRANCH=Zork
BUG=b:169217270 - Zork: SHA calculation in vboot takes too long
