[XEN][PATCH 1/8] xen/arm: split set_domain_type() between arm64/arm32

[Grygorii Strashko <grygorii_strashko@epam.com>]

From: Grygorii Strashko <grygorii_strashko@epam.com>

Split set_domain_type() between Arm64/Arm32 sub-arches as
set_domain_type() implementation is going to be extended for Arm64.

Signed-off-by: Grygorii Strashko <grygorii_strashko@epam.com>
