From: Grygorii Strashko <grygorii_strashko@epam.com>

Constify is_32/64bit_domain() macro for the case CONFIG_ARM64_AARCH32=n and
so allow compiler to opt out Aarch32 specific code.

Before (CONFIG_ARM64_AARCH32=y):
   text	   data	    bss	    dec	    hex	filename
 861672	 322412	 274976	1459060	 164374	xen-syms-before

After (CONFIG_ARM64_AARCH32=n):
   text	   data	    bss	    dec	    hex	filename
 857856	 322412	 274976	1455244	 16348c	xen-syms-after

v3:
- no changes, add tag

v2:
- use IS_ENABLED(CONFIG_ARM64_AARCH32) instead of ifdefs
