tpm: use proper locality zero SPI bus addresses
The "PC Client Protection Profile for TPM 2.0" document defines SPI
bus addresses for different localities. That definition is not honored
in the cr50 implementation, this patch fixes it: locality zero
register file is based off 0xd40000.
BRANCH=none
BUG=chrome-os-partner:54720
TEST=with the fixed cr50 image and the rest of TPM2 initialization
patches applied factory initialization sequence on Gru succeeds.
