Peter Maydell 0ca7e01cbc target-arm: Move SCTLR reset value setup to per cpu init fns
Move the reset value of SCTLR to ARMCPU, initialised in
the per-cpu init functions. It can then be reset by a
simple copy, and we can drop the code from cpu_reset_model_id().

Peter Maydell 64e1671fd4 target-arm: Move CTR setup to per cpu init fns
Move CTR (cache type register) value to an ARMCPU field
set up by per-cpu init fns.

Peter Maydell bd35c3553b target-arm: Move MVFR* setup to per cpu init fns
Move the MVFR* VFP feature register values to ARMCPU,
so they are set up by the implementation-specific instance
init functions rather than in cpu_reset_model_id().

Peter Maydell 325b3ceff6 target-arm: Move FPSID config to cpu init fns
Move the reset FPSID to the ARMCPU struct, and set it in the
per-implementation instance init function. At reset we then
just copy the reset value into the CPUARMState field.

Peter Maydell 581be09434 target-arm: Move feature bit settings to CPU init fns
Move the setting of the feature bits from cpu_reset_model_id()
to each CPU's instance init function. This requires us to move
the features field in CPUARMState so that it is not cleared
on reset.

Peter Maydell 777dc78411 target-arm: Add QOM subclasses for each ARM cpu implementation
Register subclasses for each ARM CPU implementation.

Let arm_cpu_list() enumerate CPU subclasses in alphabetical order,
except for special value "any".

Replace cpu_arm_find_by_name()'s string -> CPUID lookup by storing the
CPUID (aka MIDR, Main ID Register) value in the class.

Andreas Färber dec9c2d430 target-arm: Minimalistic CPU QOM'ification
Introduce only one non-abstract type TYPE_ARM_CPU and do not touch
cp15 registers to not interfere with Peter's ongoing remodelling.
Embed CPUARMState as first (additional) field of ARMCPU.

Let CPUClass::reset() call cpu_state_reset() for now.
