[PATCH] ARM: arch_timer: add missing include for of_* functions

[Jonathan Austin]

The arch timer code uses a bunch of of_* functions that are defined in
linux/of.h. Currently this header is not included but with CONFIG_OF defined
the functions are available anyway.

This was discovered because in the case that CONFIG_OF=n and ARM_ARCH_TIMER is
selected, the kernel no longer builds due to the lack of this header.
This patch fixes that (though without another patch
- https://patchwork.kernel.org/patch/2242291/ - the build still fails due to
a missing stub for of_find_matching_node())

It seems to me that, no matter what your opinion on whether CONFIG_OF=n with
CONFIG_ARM_ARCH_TIMER=y makes sense, we should fix this particular missing
include.
