libgloss: aarch64: Add support for Armv8-R AArch64
...
This patch adds support for Armv8-R AArch64.
Armv8-R AArch64 has no EL3, so we don't set vbar_el3, and adjust the
code to set up the MPU for Armv8-R. So build a different flavour of the
startup code to support that.
We also add a specs file that uses this alternative startup code which
can be used with Armv8-R AArch64 models.

Initialize SVE system registers.
...
This patch initializes the SVE system registers if available
and initializes the vector length to the maximum supported.
This is done according to the SVE specification [1].
