[Buildroot] [git commit branch/next] configs/andes_ae350_45: Fix build failure caused by Zicsr and Zifencei

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=4b026eb1f48fc4deabb927c351e0bca9444f466f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Don't specify the ARCH_FLAGS of U-Boot, so both extensions can be
appended to -march when building w/ gcc-12.

Fixes:
