Julien Olivain 279cd77865 arch/loongarch: add lsx/lasx SIMD dependency on fpu64

Since the LoongArch64 introduction in commit [1], the Kconfig menus
allows selecting lsx and lasx SIMD options independently of the FPU
configuration.

When lsx or lasx SIMD is selected and FPU is "none", host-gcc-initial
is failing at configuration time, with error:

    --with-simd=lasx conflicts with --with-fpu=none

According to the gcc configuration script [2], lsx and lasx values
are valid only if FPU is 64.

This commit adds the missing "depends on BR2_LOONGARCH_FPU_64" for
BR2_LOONGARCH_SIMD_LSX and BR2_LOONGARCH_SIMD_LASX options.
