This commit changes the PMSU driver to no longer map itself the CPU reset registers, and instead call into the CPU reset driver to deassert the secondary CPUs for SMP booting. In order to provide Device Tree backward compatibility, the CPU reset driver is extended to not only support its official compatible string "marvell,armada-370-cpu-reset", but to also look at the PMSU compatible string "marvell,armada-370-xp-pmsu" to find the CPU reset registers address. This allows old Device Tree to work correctly with newer kernel versions. Therefore, the CPU reset driver implements the following logic: * If one of the normal compatible strings "marvell,armada-370-cpu-reset" is found, then we map its first memory resource as the CPU reset registers. * Otherwise, if none of the normal compatible strings have been found, we look for the "marvell,armada-370-xp-pmsu" compatible string, and we map the second memory as the CPU reset registers.
