The "40nm" MIPI DSI controller found in the A100 and D1 SoCs has the
same register layout as previous SoC integrations. However, its module
clock now comes from the TCON, which means it no longer runs at a fixed
rate, so this needs to be distinguished in the driver.
The controller also now uses pins on Port D instead of dedicated pins,
so it drops the separate power domain.

Implement the fbdev's read/write helpers with the same functions. Use
the generic fbdev's code as template. Convert all drivers.
DRM's fb helpers must implement regular I/O functionality in struct
fb_ops and possibly perform a damage update. Handle all this in the
same functions and convert drivers. The functionality has been used
as part of the generic fbdev code for some time. The drivers don't
set struct drm_fb_helper.fb_dirty, so they will not be affected by
damage handling.
For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and
drm_fb_helper_cfb_write(). Several drivers require these. Until now
tegra used I/O read and write, although the memory buffer appears to
be in system memory. So use _sys_ helpers now.

The fbdev helpers implement a damage worker that forwards fbdev
updates to the DRM driver. The worker's update logic depends on
the generic fbdev emulation. Separate the two via function pointer.
The generic fbdev emulation sets struct drm_fb_helper_funcs.fb_dirty,
a new callback that hides the update logic from the damage worker.
It's not possible to use the generic logic with other fbdev emulation,
because it contains additional code for the shadow buffering that
the generic emulation employs.
DRM drivers with internal fbdev emulation can set fb_dirty to their
own implementation if they require damage handling; although no such
drivers currently exist.

log given:
[ 303.561088] Error: Driver 'ingenic-ipu' is already registered, aborting...
modprobe: ERROR: could not insert 'ingenic_drm': Device or resource busy
The reason is that ingenic_drm_init() returns platform_driver_register()
directly without checking its return value, if platform_driver_register()
failed, it returns without unregistering ingenic_ipu_driver_ptr, resulting
the ingenic-drm can never be installed later.

platform_driver_register() # ingenic_ipu_driver_ptr are registered
platform_driver_register()
driver_register()
bus_add_driver()
priv = kzalloc(...) # OOM happened
# return without unregister ingenic_ipu_driver_ptr
Fixing this problem by checking the return value of
platform_driver_register() and do platform_unregister_drivers() if
error happened.
