Now, that the MIPI DSI driver implements runtime PM, we don't need anymore to
configure clocks statically in the platform code. This patch also adds a DSITX1
clock definition for sh7372 and attaches PHY clocks to respective devices.

The PLLC2 clock was utilizing the same sort of enable/disable without
regard to usecount approach that the FSIDIV clock was when being used as
a PLL pass-through. This forces the enable/disable through the clock
framework, which now prevents the clock from being ripped out or modified
underneath users that have an existing handle on it.

On AP4EVB the card detect pin of the top SD/MMC slot is not directly
connected to the tmio/mmcif controller but to a GPIO pin, so polling
needs to be done for SDHI1 and MMCIF in order to support hotplug for
that slot. SHDI1 and MMCIF share that slot, and the used controller
is selected by a DIP switch.
This patch adds a helper function to check if a card is present in that
particular slot, registers this function with SDHI1 and MMCIF and enables
polling for SDHI1.

Add platform data, necessary to use Sony IMX074 camera sensor with AP4EVB.
Note: this does not work reliably without an API to reserve contiguous and

soon as a suitable API becomes available.

remove the io_pg_offst and phys_io members of struct machine_desc.

- LCDD2 pin which is needed for WVGA was changed to
IRQ28_123 pin on ts_get_pendown_state
- GPIO pull up on ts_init was disabled by gpio_request

This mean the return value from gpio_get_value is untrusted.

This is a preparation for HDMI hotplug support. This patch just moves all
platform defined video modes for the sh_mobile_lcdcfb driver to separate
arrays and switches all users to use element 0 of that array, so, this patch
doesn't introduce any functional changes and as such should not cause any
regressions.
