ppc: Add tcpci snk/src control via the COMMAND register
The ANX7447 has a sink/source control lines which can be connected to
a PPC. The NX20P3483 PPC requires this control to set it's sink/source
switch control. The ANX7447 contols these lines via the tcpci COMMAND
register. This CL adds new tcpm_set functions to set either SNK or SRC
control via the COMMAND register.
BUG=b:77583452
BRANCH=NONE
TEST=Tested on port 0 of Yorp with an external charger. Prior to this
CL the PPC would remain in standby state because both snk/src control
remained low. With these changes, verifed that snk_ctrl is driven high
and vbus_sink_enable() function no longer returns an error.
