[Buildroot] [PATCH] configs/aarch64_rdinfra: add new config for infra rd plaforms

[Vivek Kumar Gautam]

This defconfig enables Arm aarch64 Infra RD platforms to use
buildroot backed ramdisks to perform simple unit/sanity testing.
These infra platforms are currently enabled with a scripts based
build system as can be seen in linaro public repos[1]. A busybox
based boot is also enabled[2].
We plan to use buildroot for a richer experience while testing and
therefore this config.
This config will also be first step towards enabling buildroot
based build system for infra rd platforms in near future.
It comes with following minimal stuff -
 -neoverse_n1 cpu
 -bash shell
 -vim
 -pciutils
 -libdtc
 -screen
