With commit 4178bac4f {ARM: call of_clk_init from default time_init
handler}, of_clk_init() is always called on machines using default
time_init handler.
So drop the of_clk_init() from keystone code to avoid below
boot errors because of double call.
_of_pll_clk_init: error initializing pll mainpllclk
_of_pll_clk_init: error initializing pll papllclk
_of_pll_clk_init: error initializing pll ddr3apllclk
_of_pll_clk_init: error initializing pll ddr3bpllclk
_of_pll_clk_init: error initializing pll armpllclk

Keystone PM bus makes use of generic PM clock core backend. Since
generic PM clock core uses platform bus notifiers to track events like
ADD_DEVICE/DEL_DEVICE and to fill clock lists per each device, we need
to initialise Keystone PM domains before the platform devices have been
created.
Hence, fix it by moving keystone_pm_runtime_init() before platform
devices have been populated.

initcalls need to have platform specific checks so they are not run in
multi-platform builds.

Add runtime PM core support to Keystone SOCs by using the pm_clk
infrastructure of the PM core. Patch is based on Kevin's pm_domain
work on DaVinci SOCs.
Keystone SOC doesn't have depedency to enable clocks in early
in the boot and hence the clock and PM domain initialisation is done
at subsys_init() level.
