[PATCH 00/26] ARM: provide common arch init for DT clocks

This is a patch set based on an RFC [1][2] sent earlier to provide a common
arch/arm init for DT clock providers. Currently, the call to of_clk_init(NULL)
to initialize DT clock providers is spread among several mach-dirs. Since most
machs require DT clocks initialized before timers, no initcall can be used.
By adding of_clk_init(NULL) to arch/arm time_init(), we can remove all
mach-specific .init_time hooks that basically called of_clk_init and
clocksource_of_init.
In contrast to the RFC version, of_clk_init(NULL) is now only called if no
custom .init_time callback is set. This allows some machs to still call clock
init themselves, as not all can be converted now. Therefore, this patch sets
drops conversion of mach-mvebu and mach-zynq. New machs that were introduced
with v3.12-rc1 are also converted, except mach-u300 that requires clocks
before irqs.
The patch set is based on v3.12-rc1 and further depends on a topic branch
created by Stephen Warren for mach-tegra [3]. It is now split into preparation
and removal patches to not break bisectability. I added all Acked-by/Tested-by's
where applicable or dropped them, if the patch was separated into two.
It has been compile tested for all machs involved with the following defconfigs
(multi_v7, bcm2835, dove, exynos, kirkwood, mxs, nhk8815) and nspire selected
on multi_v4_v5.
Patches 1-8 comprise preparation patches that convert machs nomadik, prima2,
socfpga, sunxi, tegra, and vt8500 to usual .init_time callbacks calling only
of_clk_init and clocksource_of_init.
Patch 9 then introduces of_clk_init(NULL) to the arch-wide default .init_time
callback.
Patches 10-26 finally remove custom .init_time callbacks from the machs involved.
The patches have been pushed to a topic branch based on v3.12-rc1 with tegra's
tegra-for-3.13-deps-for-arm-init-time-cleanup branch merged in to
