KVM: arm64: Add get_reg_by_id() as a sys_reg_desc retrieving helper

Browse source

find_reg_by_id() requires a sys_reg_param as input, which most
users provide as a on-stack variable, but don't make any use of
the result.

Provide a helper that doesn't have this requirement and simplify
the callers (all but one).
