ASoC: codecs: Fix gain setting ranges for Renesas IDT821034 codec

The gain ranges specified in Renesas IDT821034 codec documentation
are [-3dB;+13dB] in the transmit path (ADC) and [-13dB;+3dB] in the
receive path (DAC). Allthough the registers allow programming values
outside those ranges, the signal S/N and distorsion are only
guaranteed in the specified ranges.

Set ranges to the specified ones.
