Avoid open-coding and just use the helper to encode the ID from the
sysreg table entry.
No functional change intended.

KVM: arm64: nv: Filter out unsupported features from ID regs2023-02-11T10:13:30+00:00Marc Zyngiermaz@kernel.org2023-02-09T17:58:19+00:00urn:sha1:9f75b6d447d712b6ed9abc869eedf456fe7f5e9b
As there is a number of features that we either can't support,
or don't want to support right away with NV, let's add some
basic filtering so that we don't advertize silly things to the
EL2 guest.
Whilst we are at it, advertize FEAT_TTL as well as FEAT_GTG, which
the NV implementation will implement.
