USB-PD: Make sink automatically enter EPR mode
Currently, EPR mode is entered only by 'pd' console command.
This CL makes sink ports enter EPR mode automatically.
PE_FLAGS_EPR_EXPLICIT_EXIT is cleared when soft reset is sent, a source
is disconnected, or EPR is entered again.
BUG=b:257320026,b:274929940
BRANCH=None
TEST=On Agah, plug AC, observe automatic entry to EPR. Then type 'pd 1
epr exit' and observe EPR mode is not re-entered. Then replug AC and
observe the port enters EPR automatically.
TEST=make run-usb_pd_console
