KVM: arm64: Factor out firmware register handling from psci.c

Common hypercall firmware register handing is currently employed
by psci.c. Since the upcoming patches add more of these registers,
it's better to move the generic handling to hypercall.c for a
cleaner presentation.

While we are at it, collect all the firmware registers under
fw_reg_ids[] to help implement kvm_arm_get_fw_num_regs() and
kvm_arm_copy_fw_reg_indices() in a generic way. Also, define
KVM_REG_FEATURE_LEVEL_MASK using a GENMASK instead.

No functional change intended.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"ARM:
- Proper emulation of the OSLock feature of the debug architecture

- Scalibility improvements for the MMU lock when dirty logging is on

- New VMID allocator, which will eventually help with SVA in VMs

- Better support for PMUs in heterogenous systems

- PSCI 1.1 support, enabling support for SYSTEM_RESET2

- Implement CONFIG_DEBUG_LIST at EL2

- Make CONFIG_ARM64_ERRATUM_2077057 default y

- Reduce the overhead of VM exit when no interrupt is pending

- Remove traces of 32bit ARM host support from the documentation

- Updated vgic selftests

- Various cleanups, doc updates and spelling fixes

RISC-V:
- Prevent KVM_COMPAT from being selected

- Optimize __kvm_riscv_switch_to() implementation

- RISC-V SBI v0.3 support

s390:
- memop selftest

- fix SCK locking

- adapter interruptions virtualization for secure guests

- add Claudio Imbrenda as maintainer

- first step to do proper storage key checking

x86:
- Continue switching kvm_x86_ops to static_call(); introduce
static_call_cond() and __static_call_ret0 when applicable.

- Cleanup unused arguments in several functions

- Synthesize AMD 0x80000021 leaf

- Fixes and optimization for Hyper-V sparse-bank hypercalls

- Implement Hyper-V's enlightened MSR bitmap for nested SVM

- Remove MMU auditing

- Eager splitting of page tables (new aka "TDP" MMU only) when dirty
page tracking is enabled

- Cleanup the implementation of the guest PGD cache

- Preparation for the implementation of Intel IPI virtualization

- Fix some segment descriptor checks in the emulator

- Allow AMD AVIC support on systems with physical APIC ID above 255

- Better API to disable virtualization quirks

- Fixes and optimizations for the zapping of page tables:

- Zap roots in two passes, avoiding RCU read-side critical
sections that last too long for very large guests backed by 4
KiB SPTEs.

- Zap invalid and defunct roots asynchronously via
concurrency-managed work queue.

- Allowing yielding when zapping TDP MMU roots in response to the
root's last reference being put.

- Batch more TLB flushes with an RCU trick. Whoever frees the
paging structure now holds RCU as a proxy for all vCPUs running
in the guest, i.e. to prolongs the grace period on their behalf.
It then kicks the the vCPUs out of guest mode before doing
rcu_read_unlock().

- Introduce __vcalloc and use it for very large allocations that need
memcg accounting"
