[XEN PATCH 4/5] device-tree: address violation of MISRA C Rule 5.5

[Dmytro Prokopchuk1 <dmytro_prokopchuk1@xxxxxxxx>]

Address a violation of MISRA C:2012 Rule 5.5:
"Identifiers shall be distinct from macro names".

Reports for service MC3A2.R5.5:
xen/include/xen/fdt-domain-build.h: non-compliant parameter 'copy_to_guest'
xen/include/xen/guest_access.h: non-compliant macro 'copy_to_guest'

Rename 'copy_to_guest' function parameter to 'cb' for compliance.
No functional changes.
