Current Koelsch I2C2 has 400kHz settings,
but, ak4643 audio codec chip which is connected to I2C2 can't
work such frequency.
Fixup I2C2 clock frequency to 100kHz.

Enable HS-USB device for the Lager board, defining the GPIO that the driver
should check when probing. Since this board doesn't have the OTG ID pin, we
assume that GP5_18 (USB0_PWEN) is an ID pin because it is 1 when the SW5 is
in position 2-3 (meaning USB function) and 0 in other positions.

Note that there will be pinctrl-related error messages if both internal PCI
and HS-USB drivers are enabled but they should be just ignored.

Since the PHY of USB3.0 and EHCI/OHCI ch2 are the same, the USB3.0
driver cannot use the phy driver when the EHCI/OHCI ch2 already used it:

phy phy-e6590100.usb-phy.3: phy init failed --> -16
xhci-hcd: probe of ee000000.usb failed with error -16

If so, we have to unbind the EHCI/OHCI ch2, and then we have to bind
the USB3.0 driver as the following:

  echo 0000:02:02.0 > /sys/bus/pci/drivers/ehci-pci/unbind
  echo 0000:02:01.0 > /sys/bus/pci/drivers/ohci-pci/unbind
  echo ee000000.usb > /sys/bus/platform/drivers/xhci-hcd/bind

Note that there will be pinctrl-related error messages if both
internal PCI and USB3.0 are enabled but they should be just ignored:

sh-pfc e6060000.pfc: pin GP_5_22 already requested by ee0d0000.pci; cannot claim for ee000000.usb
