irqchips: Replace __this_cpu_ptr uses
[ARM specific] These are generally replaced with raw_cpu_ptr. However, in gic_get_percpu_base() we immediately dereference the pointer. This is equivalent to a raw_cpu_read. So use that operation there. Cc: nicolas.pitre@linaro.org Cc: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Tejun Heo <tj@kernel.org>
