I2S controller has an internal mux for RCLK source clks. The list
of source clk names were passed through platform data in non-dt case.
Register the existing RCLK source clocks with clkdev using generic
connection id. This is required as part of adding DT support
for I2S controller driver.

This patch removes compatibility definitions added long time ago when
clock ids were used instead of devnames that were needed for platforms
with only one i2c controller with id -1 (some s3c24xx's).
Because currently devname field is used for matching device instances to
clocks and if no devname is provided (as in clock-s3c2412.c and
common-s3c2443.c for i2c clock, both in arch/arm/mach-s3c24xx) the clock
is being matched only by name, so s3c_device_i2c0 can always have id 0.
This patch solves the issue with i2c0 broken on boards where its the
only i2c controller used, tested on Origen.

Platform data is used to specify controller hardware specific information
such as the tx/rx fifo level mask and bit offset of rx fifo level. Such
information is not suitable to be supplied from device tree. Instead,
it can be moved into the driver data and removed from platform data.

Add entries to clocks_off for some additional clocks which are not
currently used by any mainline drivers. They default on at power up
but are never actually used so
If these blocks are actually supported some of these bindings would need
to be redone properly, for example hooking up to the muxes that use them,
but that can be done incrementally.

When the S3C64xx CPUs were converted to clkdev mappings were added for the
I2C controllers on them. On S3C6410 a device name is specified for I2C
controller 1 but not for controller 0 which makes the code less robust as
we'll falsely return the clock for controller 0 if there's an error in the
request for controller 1.
Improve things by registering a device name for controller 0 as well. Due
to the fact that we change the numbering for controller 0 depending on if
we've registered controller 1 this requires an ifdef to choose the name.
