rex: Disable config smart discharge
Disable this config, use the force discharge mode for VBUS.
With smart discharge config, fast role swap (FRS) test fails.
After FRS, Rex becomes power source. Attached device (previous
power source) sends PS_RDY request and Rex wouldn't respond.
Attached device sends soft reset/hard reset.
Hence disabling config smart discharge.
We will enable this config once FRS failure with this config
is fixed.
BUG=b:241340453
BRANCH=none
TEST=on Rex, FRS is working.
