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.
