Copy the x and y virtual resolutions from the channel information

Line pitch depends on the virtual horizontal resolution, compute it

There's no reason to use abstract operation pointers to implement the
MERAM API. Replace them by direct function calls.
Signed-off-by: NLaurent Pinchart <laurent.pinchart@ideasonboard.com>

The MERAM operations meram_register, meram_unregister and meram_update
handle LCDC cache. In preparation for "raw" MERAM allocation, rename
them to more appropriate names.

When using the MERAM the LCDC line size needs to be programmed with a
MERAM-specific value different than the real frame buffer pitch. Fix it.

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.

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.
