[XEN PATCH] xen/mem_access: address violations of MISRA C: 2012 Rule 8.4

[Alessandro Zucchelli <alessandro.zucchelli@xxxxxxxxxxx>]

Change #ifdef CONFIG_MEM_ACCESS by OR-ing defined(CONFIG_ARM),
allowing asm/mem_access.h to be included in all ARM build configurations.
This is to address the violation of MISRA C: 2012 Rule 8.4 which states:
"A compatible declaration shall be visible when an object or function
with external linkage is defined". Functions p2m_mem_access_check
and p2m_mem_access_check_and_get_page when CONFIG_MEM_ACCESS is not
defined in ARM builds don't have visible declarations in the file
containing their definitions.
