maint: avoid 'const fooPtr' in cpu files
'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can). But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).
Fix up offenders in src/cpu.
* src/cpu/cpu.h (cpuArchDecode, cpuArchEncode, cpuArchUpdate)
(cpuArchHasFeature, cpuDecode, cpuEncode, cpuUpdate)
(cpuHasFeature): Use intended type.
* src/conf/cpu_conf.h (virCPUDefCopyModel, virCPUDefCopy):
Likewise.
(virCPUDefParseXML): Drop const.
* src/cpu/cpu.c (cpuDecode, cpuEncode, cpuUpdate, cpuHasFeature):
Fix fallout.
