drm/exynos: fix accidental on-stack copy of exynos_drm_plane

[ Upstream commit 960b537e91725bcb17dd1b19e48950e62d134078 ]

gcc rightfully complains about excessive stack usage in the fimd_win_set_pixfmt()
function:

drivers/gpu/drm/exynos/exynos_drm_fimd.c: In function 'fimd_win_set_pixfmt':
drivers/gpu/drm/exynos/exynos_drm_fimd.c:750:1: error: the frame size of 1032 bytes is larger than 1024 byte
drivers/gpu/drm/exynos/exynos5433_drm_decon.c: In function 'decon_win_set_pixfmt':
drivers/gpu/drm/exynos/exynos5433_drm_decon.c:381:1: error: the frame size of 1032 bytes is larger than 1024 bytes

There is really no reason to copy the large exynos_drm_plane
structure to the stack before using one of its members, so just
use a pointer instead.

drm: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

drm: exynos: Remove #ifdef guards for PM related functions

Use the DEFINE_RUNTIME_DEV_PM_OPS(), SYSTEM_SLEEP_PM_OPS(),
RUNTIME_PM_OPS() and pm_ptr() macros to handle the runtime and suspend
PM callbacks.

These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_PM is disabled, without having
to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

drm/exynos: fimd: add BGR support for exynos4/5

In the downstream kernels for exynos4 and exynos5 devices, there is an
undocumented register that controls the order of the RGB output. It can
be set to either normal order or reversed, which enables BGR support for
those SoCs.

This patch enables the BGR support for all the SoCs that were found to
have at least one device with this logic in the corresponding downstream
kernels.

drm/exynos: Ensure suspended runtime PM state during system suspend

Add calls to pm_runtime_force_{suspend,resume} as SYSTEM_SLEEP_PM_OPS for
all drivers for the real Exynos DRM hardware modules. This ensures that
the resources will be released for the system PM suspend/resume cycle.
Exynos DRM core already takes care of suspending the whole display pipeline
before PM callbacks of the real devices are called.
