vboot_hash: Add watchdog reloads
When neither CONFIG_SHA256_HW_ACCELERATE nor CONFIG_SHA256_UNROLLED
are enabled, calculating the hash can trip the watchdog.
Add watchdog reloads at a rate of 1/2 the watchdog period when both
these options are disabled.

BRANCH=none
TEST=zmake testall
TEST=Boot zephyr-ec on Volteer, powerdown AP and observe watchdog
timeouts are fixed
