Samsung i2s driver registers the platform device twice one for the
samsung-i2s.0,1 or 2 and two for samsung-i2s.4(which actually doesn't
represent any H/W peripheral). The max number of I2S blocks on any
Samsung SoC are 3, the secondary device registration starts with
device number 4.The second time registration is for the secondary fifo
interface of a CPU dai if any exists.

With DT support the device number in the driver is always -1, I used
alias id for the above purpose.
