clkdev framework uses global mutex to protect clock tree, so it is not
possible to call clk_get() in interrupt context. This patch fixes this
issue and makes system reset by watchdog call working again.

The struct clk definition for Samsung platforms is extended to include
a instance of struct clk_lookup and a device name. When clocks are
registered using s3c24xx_register_clock function, the dev_id, con_id
and clk members are initialized with information from the struct clk
instance and struct clk_lookup member is registered.

Add s3c_disable_clocks() and change the clock registration code to use
the s3c_register_clocks() followed by s3c_disable_clocks() instead of
the loops it was using.

Turn the init sequence of
s3c24xx_register_baseclocks(xtal);
s3c64xx_register_clocks();
s3c6400_register_clocks(S3C6410_CLKDIV0_ARM_MASK);
into a single call as this is now contained within one file.

Add s3c_register_clocks() to register an array of clocks, printing
an error message if there is a problem. Replace all points in the code
where this could be used.

Reduce the size of struct clk by 12 bytes and make defining clocks with
common implementation functions easier by moving the set_rate, get_rate,
round_rate and set_parent calls into a new structure called 'struct clk_ops'
and using that instead.
This change does make a few clocks larger as they need their own clk_ops,
but this is outweighed by the number of clocks with either no ops or having
a common set of ops.
Update all the users of this.

Move the <plat/clock.h> header to plat-samsung where it can be used by all
the platforms, and readies it for the next round of clock updates where
the clock code will be amalgamated.
