hw/intc/arm_gicv3_its: Fix event ID bounds checks
In process_its_cmd() and process_mapti() we must check the
event ID against a limit defined by the size field in the DTE,
which specifies the number of ID bits minus one. Convert
this code to our num_foo convention:
* change the variable names
* use uint64_t and 1ULL when calculating the number
of valid event IDs, because DTE.SIZE is 5 bits and
so num_eventids may be up to 2^32
* fix the off-by-one error in the comparison
