uml: use PAGE_SIZE in linker scripts
This patch includes page.h header into linker scripts that allow us to
use PAGE_SIZE macro instead of numeric constant.
To be able to include page.h into linker scripts page.h is needed for
some modification - i.e. we need to use __ASSEMBLY__ and _AC macro
[jdike@linux.intel.com - fixed conflict with as-layout.h]
