rockchip: rk3308-rock-pi-s: Update defconfig

Update defconfig for rk3308-rock-pi-s with new defaults.

Add OF_LIBFDT_OVERLAY=y to support device tree overlays.

Remove the SPL_DRIVERS_MISC=y option, no misc driver is used in SPL.

Remove BOOTDELAY=0, SYS_CONSOLE_INFO_QUIET=y and enable more CMD to
allow use of U-Boot cmdline.

Add DM_ETH_PHY=y and PHY_REALTEK=y to support onboard ethernet PHY.

Add PHY_ROCKCHIP_INNO_USB2=y, DM_USB_GADGET=y and remove USB_DWC2=y to
allow full use of USB 2.0 host and otg ports.

Enable EFI_LOADER to allow EFI boot.

Also fix use of USB 2.0 otg port by removing improper use of phy-supply
and regulator-always-on props.
