efi.runtime_version is erroneously being set to the value of the
vendor's firmware revision instead of that of the implemented EFI
specification. We can't deduce which EFI functions are available based
on the revision of the vendor's firmware since the version scheme is
likely to be unique to each vendor.
What we really need to know is the revision of the implemented EFI
specification, which is available in the EFI System Table header.

drm/exynos: let drm handle edid allocations
When the system has multiple domains do_sched_rt_period_timer()
can run on any CPU and may iterate over all rt_rq in
cpu_online_mask. This means when balance_runtime() is run for a
given rt_rq that rt_rq may be in a different rd than the current
processor. Thus if we use smp_processor_id() to get rd in
do_balance_runtime() we may borrow runtime from a rt_rq that is
not part of our rd.
This changes do_balance_runtime to get the rd from the passed in
rt_rq ensuring that we borrow runtime only from the correct rd
for the given rt_rq.
This fixes a BUG at kernel/sched/rt.c:687! in __disable_runtime
when we try reclaim runtime lent to other rt_rq but runtime has
been lent to a rt_rq in another rd.

While the exynos DRM support in principle can work on
multiplatform, the FIMD and IPP sections of it both
include the plat/map-base.h header file, which is
not available on multiplatform. Rather than disabling
the entire driver, we can just conditionally build
these two parts.
Without this patch, building allyesconfig results in:
drivers/gpu/drm/exynos/exynos_drm_fimc.c:19:27: fatal error: plat/map-base.h: No such file or directory

Patch 9eb3e9e6f3 "drm/exynos: add support for ARCH_MULTIPLATFORM"
allowed building the exynos hdmi driver on non-samsung platforms,
which unfortunately broke compilation in combination with 22c4f42897
"drm: exynos: hdmi: add support for exynos5 hdmi", which added
an inclusion of the samsung-specific plat/gpio-cfg.h header file.
Fortunately, that header file is not required any more here, so
we can simply revert the inclusion in order to build the ARM
allyesconfig again without getting this error:

This patch considers DMA_NONE flag for other drivers not using
dma mapping framework with iommu such as 3d gpu driver or others.
For example, there might be 3d gpu driver that has its own iommu
hw unit and iommu table mapping mechnism. So in this case,
the dmabuf buffer imported into this driver needs just only
sg table to map the buffer with its own iommu table itself.
So this patch makes dma_buf_map_attachment ignore dma_map_sg call
and just return sg table containing pages if dma_data_direction
is DMA_NONE.

The vfl_dir field should be set to indicate whether a device can receive
data, output data or can do both. This is used to let the v4l core know
which ioctls should be accepted and which can be refused.
Unfortunately, when this field was added the radio modulator drivers were
not updated: radio modulators transmit and so vfl_dir should be set to
VFL_DIR_TX (or VFL_DIR_M2M in the special case of wl128x).
Because of this omission it is not possible to call g/s_modulator for these
drivers, which effectively renders them useless.
This patch sets the correct vfl_dir value for these drivers, correcting
this bug.

- Device tree updates for at91 dealing mostly with their new
