usb: phy: qusb2: Update tune value for host mode 



Currently driver is relying on the efuse and the tune
value passed from DT for device mode to update the TUNE1
register. Since the host mode sequence can have a different
tune value passed from DT, it should be honored too.
This change removes an extra check for tune value which will
ensure that TUNE1 register gets updated both in device and
host mode.
