The OMAP Platform code provides possibility to select GP Timer as
default clocksource instead of counter_32K by using bootcmd parameter
'clocksource', but the system will crash during early boot when this
option is used on dra7 or omap5 platforms, because it will hit BUG()
statement:
omap2_gptimer_clocksource_init
->BUG_ON(res);
This happens because clk_dev alias "sys_clkin_ck" is not registered.
Hence, fix it by adding missing "sys_clkin_ck" clk_dev aliases
definitions for omap5 and dra7.

Several exported TI clock driver features are no longer needed outside
the clock driver itself, thus move all of these to the driver private
header file. Also, update some of the driver files to actually include
this header.

The DT clock aliases for Timers use the legacy (non-DT) device
names and a source clock named sys_ck. OMAP5 is DT-boot only,
so correct the DT clock aliases to use the DT device names
instead. Also, the source clock name is corrected from 'sys_ck'
to 'timer_sys_ck', the name used by the OMAP dmtimer driver.

These modules don't need to include clk-private.h. Replace the
include with clk.h because these modules are clock consumers and
also include clk-provider.h in clk/ti.h because struct
clk_hw_omap has a struct clk_hw embedded in it.

In order to get correct clock dividers for AESS/ABE we need to set the
dpll_abe_m2x2_ck rate to be double of dpll_abe_ck.

When arch/arm/mach-omap2/gpmc.c calls clk_get(..., "fck"), it will
get a dummy clock and try to use it. As the rate is configured to zero,
this will result in several divisions by zero, and misconfigured
timings, with devices on the bus being lost in the La La Land.
It is better to remove gpmc_fck from the dummy clocks, so that gpmc.c
can fail gracefully.

USB_DPLL must be initialized and locked at boot so that

clk-54xx.c now contains the clock init functionality for omap5, including
DT clock registration and adding of static clkdev entries.
