target-alpha: Update AlphaCPU to QOM realizefn

Update the alpha_cpu_realize() signature and hook up to
DeviceClass::realize. Set realized = true in cpu_alpha_init().

qapi/error.h is included through qdev now and no longer needed.

target-arm: Update ARMCPU to QOM realizefn

Turn arm_cpu_realize() into a QOM realize function, no longer called
via cpu.h prototype. To maintain the semantics of cpu_init(), set
realized = true explicitly in cpu_arm_init().

Move GDB coprocessor registration, CPU reset and vCPU initialization
into the realizefn.

target-i386: Update X86CPU to QOM realizefn

Adapt the signature of x86_cpu_realize(), hook up to
DeviceClass::realize and set realized = true in cpu_x86_init().

The QOM realizefn cannot depend on errp being non-NULL as in
cpu_x86_init(), so use a local Error to preserve error handling behavior
on APIC initialization errors.

be called from the realizefn.

target-cris: Move TCG initialization to CRISCPU initfn

Split out TCG initialization from cpu_cris_init(). Avoid CPUCRISState
dependency for v10-specific initialization and for non-v10 by inlining
the decision into the initfn as well.
