[PATCH RFC v2 01/16] ARM: call clk_of_init from time_init

Most DT ARM machs require common clock providers initialized before timers.
Currently, arch/arm machs use .init_time to call clk_of_init right before
clocksource_of_init. This prevents to remove that hook and use the default
hook instead. clk_of_init is safe to call for non-DT platforms, so add
the call to ARM arch time_init by default. While at it, also reorder includes
alphabetically.
