As per the TCG PC Client TPM Interface Specification v1.2, bit 7 of the
access register (tmpRegValiSts bit) stays "0" until the TPM has complete
through self test and initialization. This bit is set "1" to indicate that
the other bits in the register are valid.

BUG=chrome-os-partner:35328
TEST=Booted up storm p0.2 and whirwind sp3.
Verified TPM chip is detected and reported in coreboot logs.
