rockchip: Add an I2S driver
Add a driver for I2S which allows audio data to be sent from the SoC to
the audio codec. The sample rate and other settings are hard-coded for now
as there is no suitable device-tree binding available.

Although not required, it doesn't hurt to explicitly map the USB ports to
a USB controller. Without this, the port number will be derived from the
binding order of the peripheral devices.

Most of the time SPL only needs very simple FAT reading, so having

configs: am335x_evm: enable DM_USB_GADGET and USB_ETHER in u-boot and SPL
The AM335x ROM boot is able to download the SPL from a RNDIS connection
on USB0. To enable a full RNDIS boot flow (romboot -> SPL -> u-boot -> ..),
we can use USB_ETHER in SPL and u-boot.
However this increase the size of the SPL past its limit. So removing the
unused SPL_EXT_SUPPORT.

usb: ether: call _usb_eth_halt() if initialization fails
If the host does not respond in time, the initialization fails. However
the usb ether driver will still be registered. This will make
usb_gadget_probe_driver() fail the next time the initialization is
attempted because it cannot find an available UDC.
Fixing this by calling _usb_eth_halt() when the init fails.
