hw/intc/arm_gicv3: fix an extra left-shift when reading IPRIORITYR
...
When either GICD_IPRIORITYR or GICR_IPRIORITYR is read as a 32-bit
register, the post left-shift operator in the for loop causes an
extra shift after the least significant byte has been placed.
The 32-bit value actually returned is therefore the expected value
shifted left by 8 bits.

hw/intc/arm_gicv3: Make reserved register addresses RAZ/WI
...
The GICv3 specification says that reserved register addresses
should RAZ/WI. This means we need to return MEMTX_OK, not MEMTX_ERROR,
because now that we support generating external aborts the
latter will cause an abort on new board models.

hw/intc/arm_gicv3: Fix compilation with simple trace backend
...
Fix missing includes of qemu/log.h, which broke compilation with the
simple trace backend (the default backend pulls in log.h implicitly
via trace.h).

[PMM: significantly overhauled/rewritten:
* use the new bitmap data structures
* restructure register read/write to handle different width accesses
natively, since almost all registers are 32-bit only, rather
than implementing everything as byte accesses
* implemented security extension support
