Alec Berg 1599e7a6f1 glados_pd: oak_pd: fix PD tx_disable timing
Disabling CC TX_DATA needs to be very fast to avoid clocking out
an extra garbage bit at the end of transmit. This change fixes
pd_tx_disable() to disable the TX_DATA line as fast as possible.

BUG=chrome-os-partner:40920
BRANCH=none
TEST=test on glados with scope attached to CC. note before this
change we occasionally get a garbage bit at the end of CC transmit.
With this change, it looks clean.
