configs/qemu_aarch64_sbsa_defconfig: switch to neoverse-n1 (armv8.2a)
The SBSA Reference Platform was updated to neoverse-n1 (armv8.2a) in
Qemu v8.1 [1].

Tests test_fwts.py test_edk2.py using
BR2_TARGET_EDK2_PLATFORM_QEMU_SBSA=y are not updated to neoverse-n1 by
this commit. Those tests were disabled in a previous commit. Those
tests will be updated and fixed in followup commits.
Note: SBSA Reference Platform was recently updated again to neoverse-n2
(armv9.0a) in Qemu v9.1 [2]. But there is no armv9.0a support yet in
Buildroot.
