Martin Roth 8839b7f109 security/vboot: Add Kconfig symbol to set hashing block size
Generally, this size probably doesn't matter very much, but in the
case of picasso's psp_verstage, the hash is being calculated by
hardware using relatively expensive system calls.  By increasing the
block size, we can save roughly 140ms of 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
