6f5a8c6b25 drivers/i2s/i2schar: Implement ioctl commands for i2schar 
This commit implements a set of commands to the i2s character
driver. The implemented commands allows getting and setting
parameters like data width, sample rate and number of channels for
both receiver and transmitter. If no ioctl is found, the command
is redirected to the lower driver implementation if it has the
ioctl callback registered.
