Currently we check to make sure there is no error state on the extcon
handle for VBUS when writing to the HS_PHY_GENCONFIG_2 register. When using
the USB role-switch API we still need to write to this register absent an
extcon handle.
This patch makes the appropriate update to ensure the write happens if
role-switching is true.
