Similar to commit 1c11289b34 ("peci: cpu: Fix use-after-free in
adev_release()"), the auxiliary device is not torn down in the correct
order. If auxiliary_device_add() fails, the release callback will be
called twice, resulting in a UAF. Due to timing, the auxdev code in this
driver "took inspiration" from the aforementioned commit, and thus its
bugs too!
Moving auxiliary_device_uninit() to the unregister callback instead
avoids the issue.

Currently, the regulator framework informs us before calling into
their unused cleanup paths, which eases at least some debugging. The
same could be beneficial for clocks, so that random shutdowns shortly
after most initcalls are done can be less of a guess.
Add a pr_info before disabling unused clocks to do so.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Each entry in the clock table specifies a number of individual bits in
registers, for contolling clock reset, gaiting, etc. These reg/bit were
packed into a u16 to save space. The combined value is difficult to
understand when reviewing the clock table entries.
Introduce a "struct regbit" which still occupies only 16 bits, but
allows the register and bit values to be specified explicitly. Convert
all previous uses of u16 for reg/bit into "struct regbit".
The bulk of this patch converts the clock table to use struct regbit,
making use of the RB() helper macro. The conversion was automated by
script, and as a further verification, the compiled binary of the table
was compared before/after the change (with objdump -D).
The clk_rdesc_set() function now checks for zero reg/bit internally.
This allows callers of that function to remove those checks.

kdiv is a signed 16 bit value in the DEV_CTL1 register. Commit
53990cf9d5 ("clk: imx: pll14xx: consolidate rate calculation") changed
the kdiv variable from a short int to just int. When the value read from
the DIV_CTL1 register is assigned directly to an int the sign of the value
is lost resulting in incorrect results when the value is negative. Adding
a s16 cast to the register value fixes the issue.

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.
See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
description of which machines were marked unused and are now removed. The
only removals that got postponed are Terastation WXL (mv78xx0) and
Jornada720 (StrongARM1100), which turned out to still have potential
users.
