arm64: rename ARM64_HAS_SYSREG_GIC_CPUIF to ARM64_HAS_GIC_CPUIF_SYSREGS

Subsequent patches will add more GIC-related cpucaps. When we do so, it
would be nice to give them a consistent HAS_GIC_* prefix.

In preparation for doing so, this patch renames the existing
ARM64_HAS_SYSREG_GIC_CPUIF cap to ARM64_HAS_GIC_CPUIF_SYSREGS.

The 'CPUIF_SYSREGS' suffix is chosen so that this will be ordered ahead
of other ARM64_HAS_GIC_* definitions in subsequent patches.

The cpucaps file was hand-modified; all other changes were scripted
with:

find . -type f -name '*.[chS]' -print0 | \
xargs -0 sed -i
's/ARM64_HAS_SYSREG_GIC_CPUIF/ARM64_HAS_GIC_CPUIF_SYSREGS/'

There should be no functional change as a result of this patch.
