[PATCH] ARM: scu: Should include asm/errno.h

[Dave Gerlach]

The stub for scu_power_mode returns -EINVAL if a !CONFIG_SMP build is
being done, and because this file can be included in files that are
shared between SMP and non-SMP platforms, we must make sure to
explicitly include asm/errno.h otherwise the build may fail based on
include order.
