usb: typec: tipd: drop second firmware name read

tps_request_firmware() reads the firmware name and there is no need to
repeat the action in the device-specific implementations of the firmware
update mechanism.

Provide the firmware name as a parameter in tps_request_firmware() to
avoid repetitive operations in the device-specific implementations.
