phy: Extend generic_setup_phy() with PHY mode and submode

Extend generic_setup_phy() parameter list with PHY mode and submode and
call generic_phy_set_mode() in generic_setup_phy(), so the generic PHY
setup function can configure the PHY into correct mode before powering
the PHY up.

Update all call sites of generic_setup_phy() as well, all of which are
USB host related, except for DM test which now behaves as a USB host
test.

Note that if the PHY driver does not implement the .set_mode callback,
generic_phy_set_mode() call returns 0 and does not error out, so this
should not break any existing systems.
