Subject: [PATCH 1/2] arm64: smp: Include smp_plat.h from smp.h

Most architectures provide the cpu_logical_map[] definition as part of
asm/smp.h, which is included by linux/smp.h. For irqchip drivers that
work across a variety of platforms (MIPS, ARM, ARM64, etc.), and making
use of cpu_logical_map[] this avoids making any architecture specific
include in those drivers.

smp_plat.h uses -EINVAL, so make sure that header file include
linux/errmo.h.
