d1aae06630 clk: starfive: Avoid casting iomem pointers
Let's use a wrapper struct for the auxiliary_device made in
jh7110_reset_controller_register() so that we can stop casting iomem
pointers. The casts trip up tools like sparse, and make for some awkward
casts that are largely unnecessary. While we're here, change the
allocation from devm and actually free the auxiliary_device memory in
the release function. This avoids any use after free problems where the
parent device driver is unbound from the device but the
auxiliuary_device is still in use accessing devm freed memory.

7455b7007b clk: microchip: fix potential UAF in auxdev release callback
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.

Pull Starfive clk driver updates from Conor Dooley:

 - Initial JH7110 clk/reset support

A rake of patches, initially worked on by Emil & later picked up by Hal
that add support for the sys/aon clock & reset controllers on StarFive's
JH7110 SoC.

This SoC is largely similar to the existing JH7100, so a bunch of
refactoring is done to share as many bits as possible between the two.
What's here (plus the already applied pinctrl bits) should be sufficient
to boot a basic initramfs.

b6d7406cd7 reset: starfive: jh71x0: Use 32bit I/O on 32bit registers
We currently use 64bit I/O on the 32bit registers. This works because
there are an even number of assert and status registers, so they're only
ever accessed in pairs on 64bit boundaries.

There are however other reset controllers for audio and video on the
JH7100 SoC with only one status register that isn't 64bit aligned so
64bit I/O results in an unaligned access exception.

Switch to 32bit I/O in preparation for supporting these resets too.

1ec3d20e4e reset: starfive: Factor out common JH71X0 reset code
The StarFive JH7100 SoC has additional reset controllers for audio and
video, but the registers follow the same structure. On the JH7110 the
reset registers don't get their own memory range, but instead follow the
clock control registers. The registers still follow the same structure
though, so let's factor out the common code to handle all these cases.
