Latest SuperH HDMI allows 32bit access only.
But the data is 8bit. So, we can keep compatibility by switching 8/32 bit access.

The HDMI clock has to be reconfigured for different video modes. However, the
precision of the supplying SoC clock on SH-Mobile systems is often
insufficient. This patch allows to additionally reconfigure the parent clock
to achieve the optimal HDMI clock frequency, in case this is supported by the
platform.

Some SH-Mobile SoCs have an HDMI controller and a PHY, attached to one of their
LCDC interfaces. This patch adds a preliminary static support for such
controllers, this means, that only the 720p mode is handled ATM. Support for
more modes and a dynamic switching between them will be added by a follow up
patch.
