cpu: Apply the ARM TLB rework to the checker CPU.
The TLBs now create the stage 2 MMUs as children, and since those are
specialized for instruction and data, the CPU needs to use ArmITB or
ArmDTB instead of ArmTLB which is the base class without an MMU. This
was changed for the BaseCPU already, but the TLBs are added in the
checker CPU as well.
