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().

Move CTR (cache type register) value to an ARMCPU field
set up by 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().

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.

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.

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.

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.
