Subject: [PATCH RFC v3 13/27] KVM: arm64: Rename sve_state_reg_region

As for SVE we will need to pull parts of dynamically sized registers out of
a block of memory for SME so we will use a similar code pattern for this.
Rename the current struct sve_state_reg_region in preparation for this.

No functional change.
