selftest/arm64: Fix sve2p1_sigill() to hwcap test
[ Upstream commit d87c828daa7ead9763416f75cc416496969cf1dc ]
The FEAT_SVE2p1 is indicated by ID_AA64ZFR0_EL1.SVEver. However,
the BFADD requires the FEAT_SVE_B16B16, which is indicated by
ID_AA64ZFR0_EL1.B16B16. This could cause the test to incorrectly
fail on a CPU that supports FEAT_SVE2.1 but not FEAT_SVE_B16B16.
LD1Q Gather load quadwords which is decoded from SVE encodings and
implied by FEAT_SVE2p1.
