[XEN PATCH] xen/arm: smmu: move phys_addr_t definition to linux-compat.h

[Federico Serafini <federico.serafini@bugseng.com>]

Both smmu and smmu-v3 (ported from Linux) define the typedef name
"phys_addr_t": move the type definition to the common header
linux-compat.h to address violations of MISRA C:2012 Rule 5.6
("A typedef name shall be a unique identifier").
No functional change.
