Samsung SoC drivers changes for v5.11
1. Limit the big.LITTLE cpuidle driver to Peach-Pit/Pi Chromebooks only
because these are the only platforms were the driver works properly.
2. Convert the Exynos CLKOUT driver to a full module which solves
boot-probe ordering issues (e.g. if device nodes in DTS are moved).
This also brings modularization and compile testing.

Allwinner MBUS and DMA-ops rework
The Allwinner SoCs have a number of high-bandwidth devices connected to
a memory bus with a different RAM mapping than the CPU.
This was addressed before through drivers setting the DMA offsets
directly, and subsequently changed to calls to dma_direct_set_offset.
However that wasn't really meant to be exported to modules (and thus
drivers). The duplicated code also led to small inconsistencies across
drivers in how we dealt with DT backward compatibility.
Move all that DMA setup code into a platform bus notifier to share that
code and remove the export on dma_direct_set_offset.

firmware: tegra: fix strncpy()/strncat() confusion
The way that bpmp_populate_debugfs_inband() uses strncpy()
and strncat() makes no sense since the size argument for
the first is insufficient to contain the trailing '/'
and the second passes the length of the input rather than
the output, which triggers a warning:
In function 'strncat',
inlined from 'bpmp_populate_debugfs_inband' at ../drivers/firmware/tegra/bpmp-debugfs.c:422:4:

The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as
the DMA usage of these drivers was "interesting" and the security
people were starting to question some issues that were starting to be
found in the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of
other vendors were wanting to solve. But as-is, this codebase didn't

"Fixes all over the place.
A new UAPI is borderline: can also be considered a new feature but
also seems to be the only way we could come up with to fix addressing
for userspace - and it seems important to switch to it now before
userspace making assumptions about addressing ability of devices is
set in stone"
