[Buildroot] [PATCH 1/1] package/rpi-userland: add support for aarch64

[Tim Gover]

Enable aarch64 support for rpi-userland to provide
vcmailbox and vcgencmd in 64bit builds. The are useful
for programming OTP and system debug.

The ARM64=ON parameter restricts the make targets
to only include those supported on 64-bit i.e. it
excludes the legacy Broadcom EGL drivers.
