firmware: turris-mox-rwtm: Add support for ECDSA signatures with HW private key

Add support for digital message signing with the private key stored in
the rWTM secure coprocessor. Turris Mox devices have an ECDSA private
key generated and burned into rWTM eFuses when manufactured. This
private key is not readable from the rWTM, but rWTM firmware allows for
signing messages with it and retrieving the public key.

This is exposed to userspace via the keyctl API.

User can find the key by either looking at /proc/keys or listing the
keyring:

$ cat /proc/keys

$ keyctl rlist %:.turris-signing-keys

To get the public key:

$ keyctl read 889166537
67 bytes of data in key:

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Will Deacon:
"The headline feature is the re-enablement of support for Arm's
Scalable Matrix Extension (SME) thanks to a bumper crop of fixes
from Mark Rutland.

If matrices aren't your thing, then Ryan's page-table optimisation
work is much more interesting.

Summary:

ACPI, EFI and PSCI:

- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree

- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls

- Fix a node refcount imbalance in the PSCI device-tree code

CPU Features:

- Ensure register sanitisation is applied to fields in ID_AA64MMFR4

- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
guests can reliably query the underlying CPU types from the VMM

- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code

Entry code:

- Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
selected

Memory management:

- Prevent BSS exports from being used by the early PI code

- Propagate level and stride information to the low-level TLB
invalidation routines when operating on hugetlb entries

- Use the page-table contiguous hint for vmap() mappings with
VM_ALLOW_HUGE_VMAP where possible

- Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
and hook this up on arm64 so that the trailing DSB (used to publish
the updates to the hardware walker) can be deferred until the end
of the mapping operation

- Extend mmap() randomisation for 52-bit virtual addresses (on par
with 48-bit addressing) and remove limited support for
randomisation of the linear map

Perf and PMUs:

- Add support for probing the CMN-S3 driver using ACPI

- Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers

Selftests:

- Fix FPSIMD and SME tests to align with the freshly re-enabled SME
support

- Fix default setting of the OUTPUT variable so that tests are
installed in the right location

vDSO:

- Replace raw counter access from inline assembly code with a call to
the the __arch_counter_get_cntvct() helper function

Miscellaneous:

- Add some missing header inclusions to the CCA headers

- Rework rendering of /proc/cpuinfo to follow the x86-approach and
avoid repeated buffer expansion (the user-visible format remains
identical)

- Remove redundant selection of CONFIG_CRC32

- Extend early error message when failing to map the device-tree
blob"

firmware: SDEI: Allow sdei initialization without ACPI_APEI_GHES

SDEI usually initialize with the ACPI table, but on platforms where
ACPI is not used, the SDEI feature can still be used to handle
specific firmware calls or other customized purposes. Therefore, it
is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES.

In commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES
in acpi_init()"), to make APEI ready earlier, sdei_init was moved
into acpi_ghes_init instead of being a standalone initcall, adding
ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the
flexibility and usability of SDEI.

This patch corrects the dependency in Kconfig and splits sdei_init()
into two separate functions: sdei_init() and acpi_sdei_init().
sdei_init() will be called by arch_initcall and will only initialize
the platform driver, while acpi_sdei_init() will initialize the
device from acpi_ghes_init() when ACPI is ready. This allows the
initialization of SDEI without ACPI_APEI_GHES enabled.
