arm64/cpuinfo: Remove references to reserved cache type

Browse source

In 155433cb36 ("arm64: cache: Remove support for ASID-tagged VIVT
I-caches") we removed all the support fir AIVIVT cache types and renamed
all references to the field to say "unknown" since support for AIVIVT
caches was removed from the architecture. Some confusion has resulted since
the corresponding change to the architecture left the value named as
AIVIVT but documented it as reserved in v8, refactor the code so we don't
define the constant instead. This will help with automatic generation of
this register field since it means we care less about the correspondence
with the ARM.

No functional change, the value displayed to userspace is unchanged.
