bd1cefdd9f target-arm: remove uses of cpu_interrupt() for user-mode emulation
Arm leaves around some functions that use cpu_interrupt(), even for
user-mode emulation when the code is unreachable.  Pull out the
system-mode implementation to a separate file, and add stubs for
CONFIG_USER_ONLY.

87511341c3 add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wide
The helpers form load-acquire/store-release pair and ensure
that appropriate barriers are in place in case checks happen
outside of BQL.

Use them to replace open-coded checkers/setters across the code,
to make sure that barriers are not missed.  Helpers also make code a
bit more readable.

0ab97bc070 target/arm: Move aarch64 CPU property code to TYPE_ARM_CPU
The only thing we have left in the TYPE_AARCH64_CPU class that makes
it different to TYPE_ARM_CPU is that we register the handling of the
"aarch64" property there.

Move the handling of this property to the base class, where we make
it a property of the object rather than of the class, and add it
to the CPU if it has the ARM_FEATURE_AARCH64 property present at
init.  This is in line with how we handle other Arm CPU properties,
and should not change which CPUs it's visible for.

bae9fb4b01 target/arm: Handle AArch64 in TYPE_ARM_CPU gdb_arch_name
Instead of having the TYPE_AARCH64_CPU subclass set
CPUClass::gdb_arch_name to a different function, make the
TYPE_ARM_CPU implementation of the method handle AArch64.

For the moment we make the "is this AArch64?" function test "is the
CPU of TYPE_AARCH64_CPU?", so that this produces no behavioural
change.  When we've moved all the gdbstub related methods across to
the base class, we will be able to change this to be "does the CPU
have the ARM_FEATURE_AARCH64 feature?".

f9f99d7ca5 target/arm: Implement SEL2 physical and virtual timers
When FEAT_SEL2 was implemented the SEL2 timers were missed. This
shows up when building the latest Hafnium with SPMC_AT_EL=2. The
actual implementation utilises the same logic as the rest of the
timers so all we need to do is:

  - define the timers and their access functions
  - conditionally add the correct system registers
  - create a new accessfn as the rules are subtly different to the
    existing secure timer
