This series fixes two classes of board-level issues found while
bringing up several RK3568 boards.

The first four patches address GMAC clock parents. On these boards the
DTS lists SCLK_GMACx in assigned-clocks but only provides a parent for
SCLK_GMACx_RX_TX, so SCLK_GMACx keeps whatever parent the bootloader or
the hardware reset left. Add CLK_MACx_2TOP explicitly so the GMAC main
clock always comes from the internal source. BPI-R2 Pro additionally
describes clock_in_out wrongly ("input" while the port is a fixed-link
with no external 125 MHz clock); switch it to "output" to match the
hardware. On RK3568 clock_in_out does not change the hardware clock
routing today, so that part is a description fix.

The last patch fixes USB OTG power on the Ariaboard Photonicat. On
battery power the USB port is dead because usb2phy0_otg is fed from a
regulator that only exists when the DC input is present. Add a boost
regulator gated by the existing vcc5v0_usb30_otg0 rail and switch the
PHY supply to it, restoring USB host functionality on battery.
