Add ALSA based HDMI AHB audio driver for dw_hdmi. The only buffer
format supported by the hardware is its own special IEC958 based format,
which is not compatible with any ALSA format. To avoid doing too much
data manipulation within the driver, we support only ALSAs IEC958 LE and
24-bit PCM formats for 2 to 6 channels, which we convert to its hardware
format.
A more desirable solution would be to have this conversion in userspace,
but ALSA does not appear to allow such transformations outside of
libasound itself.

I2CM_ADDRESS became a MESS, fix it, also change guarding define
to __DW_HDMI_H__ , since the driver is not IMX specific.

the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi
