Latest SuperH HDMI uses not only HDMI Core Register (HTOP0)
but also HDMI Control Register (HTOP1).
This patch adds HDMI Control Register support.

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

This patch fixes max loop count in EQ(Channel Equalization) sequence
of link training. According to DP(displayport) specification,
the max loop count in this sequence should be 5.

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."
Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

sh_mipi uses some clocks, but the method of setup depends on CPU.
Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.
But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f0
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.
This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

The meram_register(), meram_unregister() and meram_update() operations
check that the pointers they get from the caller are not NULL. Those
checks can be remove, as the caller already ensures that the pointers
are valid.
The platform sanity checks can also be removed, as the operations can't
be accessed without valid platform data anyway.

Remove the RGB or Y/C base address update from the meram_register()
operation, as this belongs to the meram_update() operation.

Instead of copying the whole platform data structure to struct
sh_mobile_lcdc_chan, store a const pointer to the channel platform data.
MERAM configuration information needs to be changed at runtime, so copy
it to struct sh_mobile_lcdc_chan.

Instead of manually specifying the ICBs to use in platform data,
allocate them automatically at runtime. The range of reserved ICBs (for
instance to be used through UIO), if any, is passed in the platform data
reserved_icbs field as a bitmask.
The MERAM registration function now returns a pointer to an opaque MERAM
object, which is passed to the update and unregistration functions.

The new structure stores ICB parameters for ICBs.
Instead of modifying the struct sh_mobile_meram_cfg instances passed by
callers, store the ICB parameters internally and make the public API
take const pointers to sh_mobile_meram_cfg.
