The register definitions for VMIDR and VMPIDR have separate
reginfo structs for the AArch32 and AArch64 registers. However
the 32-bit versions are wrong:
* they use offsetof instead of offsetoflow32 to mark where
the 32-bit value lives in the uint64_t CPU state field
* they don't mark themselves as ARM_CP_ALIAS
In particular this means that if you try to use an Arm guest CPU
which enables EL2 on a big-endian host it will assert at reset:
target/arm/cpu.c:114: cp_reg_check_reset: Assertion `oldvalue == newvalue' failed.
because the reset of the 32-bit register writes to the top
half of the uint64_t.
Correct the errors in the structures.

This is necessary for 'make check' to pass on big endian
systems with the 'raspi3' board enabled, which is the
first board which has an EL2-enabled-by-default CPU.
