Some I2S clocks may require some time to get the clock ready
for operation and so need to be prepared before they are enabled.
So, prepare the clock as well as enabling it, but combine the
two through clk_prepare_enable.

The I2S block provides component parameter registers which
describe how the block is instantiated.  Use these registers
to extract the block's configuration rather than relying on
platform data.

Move code that configures the DAI and DMA into a separate function.  This
reduces the size of the dw_i2s_probe function and will make it easier to
add support for device tree to the driver.

Prepare for the introduction of device-tree support by re-ordering some
of the allocations and using devm_iomap_resource to simplify IO mapping.

There were missing break statements so everything used
TWO_CHANNEL_SUPPORT.

Also I added a return statement to silence a GCC warning:
