[Buildroot] [PATCH 5/5] sunxi-mali-mainline-driver: add support for building on arm64(aarch64) architecture.

[Giulio Benetti]

Since Blobs for arm64(aarch64) are available at Bootlin Github and
sunxi-mali-mainline has been updated to support them, add support for
building on arm64(aarch64).

Check if BR2_arm or BR2_aarch64 is enabled and only in BR2_arm case
expect BR2_ARM_EABIHF to be enabled.
Add ARCH=arm or ARCH=arm64 to SUNXI_MALI_MAINLINE_DRIVER_MAKE_OPTS
to build for the right architecture with build.sh script provided on
Maxime Ripard sunxi-mali repository.
