In the ARMCPRegInfo definitions for the GICv3 CPU interface
registers, we were trying to use .fieldoffset to specify
the locations of data fields within the GICv3CPUState struct.
This is completely broken, because .fieldoffset is for offsets
into the CPUARMState struct. We didn't notice because we
were only using this for reads to BPR0, AP0R<n>, IGRPEN0
and CTLR_EL3, and Linux doesn't use these registers.
Replace the .fieldoffset uses with explicit read functions.

Fix some problems with the tracepoints for ICC register reads
and writes:
* tracepoints for ICC_BPR<n>, ICC_AP<n>R<x>, ICC_IGRPEN<n>,
ICC_EIOR<n> were not printing the <n> that indicated whether
the access was to the group 0 or 1 register
* the ICC_IGREPEN1_EL3 read function was not actually calling
the associated tracepoint
* the ICC_BPR<n> write function was incorrectly calling the
tracepoint for ICC_PMR writes

Implement the CPU interface registers for the GICv3; these are
CPU system registers, not MMIO registers.
This commit implements all the registers which are simple
accessors for GIC state, but not those which act as interfaces
for acknowledging, dismissing or generating interrupts. (Those
will be added in a later commit.)
