ARM: shmobile: convert logical CPU numbers to physical numbers
This patch uses the new cpu_logical_map() macro for converting logical CPU numbers into physical numbers when dealing with the SCU in the SMP boot path for sh73a0. Cc: Magnus Damm <magnus.damm@gmail.com> Cc: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
