anx3429: read chip firmware version during init
fetching the chip firmware version toward the end of the chip
anx74xx_tcpm_init() sequence is a good place to do this. we need this
info in any case and this is a safe place to access device registers
and cache the values. subsequent chip firmware queries typically
return the cached value. also, tcpci_tcpm_init() is already
structured this way.
TEST=verified with follow-up CL that firmware update succeeds and new
version is reported
BRANCH=none
BUG=b:35586895
