pd: Cleanup usb_pd low power idle sleep mask
Add a new define CONFIG_USB_PD_LOW_POWER_IDLE_WHEN_CONNECTED that
indicates the chip should try to go to low power idle even when a PD
connection is established -- this is the current behavior only for
Zinger.
Also, enable and disable the sleep mask bit from tcpc on rx enable /
disable.
BUG=chrome-os-partner:45010
TEST=Manual on glados / glados_pd. Insert Zinger, verify that glados_pd
stays out of low power idle. Remove Zinger, verify that glados_pd
resumes going into low power idle.
BRANCH=None
