The only thing that socfpga_init_clocks was doing is setting up the smp_twd clk.
Now that twd-timer's clock phandle is populated in the DTS, we can remove
this function.

The clk manager's base address was being mapped in SOCFPGA's arch code and
being extern'ed out to the clock driver. This method is not correct, and the
arch code was not really doing anything with that clk manager anyways.

This patch moves the mapping of the clk manager's base address in the clock
driver itself. Cleans up CLK_OF_DECLARE() into a single registration of all
the clocks.

v2: Use a static declaration for the clk_mgr_base_addr. Clean up the
    CLK_OF_DECLARE() as suggested by Arnd.

With arch/arm calling of_clk_init(NULL) from time_init(), we can now
remove custom .init_time hooks.

Current socfpga board init calls of_clk_init() from .machine_init. To
allow consolidation of DT driven .time_init, move of_clock_init() to
a temporary .time_init that will be removed when arch-wide callback is
available.

dw_apb_timer_init used to search the devicetree for matching timer
devices, making calls to it from board files necessary.

Change the dw_apb_timer_init to work with CLOCKSOURCE_OF_DECLARE.
With this change the function gets called once for each timer node
and tracks these number of calls to attach clockevent and clocksource
devices to the nodes.

Also remove the calls to dw_apb_timer_init from all previous users, as
clocksource_of_init is the default for init_time now.

Tested on the upcoming rk3066 code.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
