Unimplemented clock operations should be simply omitted instead of returning
error values.
This patch removes unimplemented PLL operations to fix problems caused
by returning error code in round_rate callback.

Many clock muxes of Exynos 4x12 uses mout_mpll_user_* clocks instead of
sclk_mpll as one of their parents.
This patch moves such clocks from common array into SoC-specific arrays
and adjusts their parent lists respectively.

The current code adds aliases, if necessary, directly when adding
the clock, limiting the number of possible aliases to one.
Some platforms need more than one alias, like the hsmmc pclocks on
s3c2416 which need a "hsmmc" and "mmc_busclk.0" alias for the s3c-
sdhci driver.
Therefore add the possibility to separately add clock aliases for
previously created clocks.

The clock_init function checked for a dt node, returning immediately
for non-dt machines. This let to the suspend init never being reached
on those non-DT machines.
So fix this by moving the pm init code above the check.

On some Samsung platforms divider clocks only use specific divider
combinations like the armdiv on s3c2443 and s3c2416. For these
usecases the generic divider clock already provides the option of
providing a lookup table mapping register values to divider values.
Therefore add a new field to samsung_div_clock and if filled with a
table, use clk_register_divider_table instead of clk_register_divider
to register a divider clock

The clock frequency of xxti and xusbxti clocks is dependent on the

clocks. So allow the frequency of these clocks to be specfied from

Since the clock initialization should be completed prior to the mct
timer initialization, create a new function 'exynos_init_time' that
first sets up the clock and then invokes the timer initialization
function. The 'init_time' callback in the board files are updated to
invoke this new wrapper function.
