arm64: efi: Add missing Kconfig dependency on KERNEL_MODE_NEON
The EFI runtime services ABI permits calls to EFI to clobber
certain FPSIMD/NEON registers, as per the AArch64 procedure call
standard.
Saving/restoring the clobbered registers around such calls needs
KERNEL_MODE_NEON, but the dependency is missing from Kconfig.
This patch adds the missing dependency.
This will aid bisection of the patches implementing support for the
ARM Scalable Vector Extension (SVE).
