usb: typec: tipd: Separate reset for TPS6598x
Some platforms like SK-AM62, SK-AM62A cannot boot up to prompt if
TPS6598x is cold-reset during unconditionally on probe failures by
sending "GAID" sequence.
The probe can fail initially because USB0 remote-endpoint may not be
probed yet, which defines the usb-role-switch property.
Fixes: d49f90822015 ("usb: typec: tipd: add init and reset functions to tipd_data")
Closes: https://lore.kernel.org/linux-usb/vmngazj6si7xxss7txenezkcukqje2glhvvs7ipdcx3vjiqvlk@ohmmhhhlryws/
