ASoC: Updates for v6.6

Here's an initial batch of updates for ASoC for this release cycle.
We've got a bunch of new drivers in here, a bit of core work from
Morimoto-san and quite a lot of janitorial work. There's several
updates that pull in changes from other subsystems in order to build
on them:

- An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
some IIO changes.
- Create a library function for intlog10() and use it in the NAU8825
driver.
- Include the ASoC tests, including the topology tests, in the default
KUnit full test coverage. This also involves enabling UML builds of
ALSA since that's the default KUnit test environment which pulls in
the addition of some stubs to the driver.
- More factoring out from Morimoto-san.
- Convert a lot of drivers to use the more modern maple tree register
cache.
- Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic
CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.

KVM: arm64: Add missing BTI instructions

Some bti instructions were missing from
commit b53d4a272349 ("KVM: arm64: Use BTI for nvhe")

KVM: arm64: Add missing BTI instructions

Some bti instructions were missing from
commit b53d4a272349 ("KVM: arm64: Use BTI for nvhe")

1) kvm_host_psci_cpu_entry
kvm_host_psci_cpu_entry is called from __kvm_hyp_init_cpu through "br"
instruction as __kvm_hyp_init_cpu resides in idmap section while
kvm_host_psci_cpu_entry is in hyp .text so the offset is larger than
128MB range covered by "b".
Which means that this function should start with "bti j" instruction.

LLVM which is the only compiler supporting BTI for Linux, adds "bti j"
for jump tables or by when taking the address of the block [1].
Same behaviour is observed with GCC.

As kvm_host_psci_cpu_entry is a C function, this must be done in
assembly.

Another solution is to use X16/X17 with "br", as according to ARM
ARM DDI0487I.a RLJHCL/IGMGRS, PACIASP has an implicit branch
target identification instruction that is compatible with
PSTATE.BTYPE 0b01 which includes "br X16/X17"
And the kvm_host_psci_cpu_entry has PACIASP as it is an external
function.
Although, using explicit "bti" makes it more clear than relying on
which register is used.

A third solution is to clear SCTLR_EL2.BT, which would make PACIASP
compatible PSTATE.BTYPE 0b11 ("br" to other registers).
However this deviates from the kernel behaviour (in bti_enable()).

2) Spectre vector table
"br" instructions are generated at runtime for the vector table
(__bp_harden_hyp_vecs).
These branches would land on vectors in __kvm_hyp_vector at offset 8.
As all the macros are defined with valid_vect/invalid_vect, it is
sufficient to add "bti j" at the correct offset.
