drm/amd/amdgpu: Added a quirk for Stoney platform
Added DW_I2S_QUIRK_16BIT_IDX_OVERRIDE quirk for Stoney. Supported format and bus width for I2S controller read from I2S Component Parameter registers. These are ready only registers. For Stoney, I2S Component Parameter registers are programmed to support 32 bit format and 4 bytes bus width only. By setting this quirk,It will override 32 bit format with 16 bit format and 2 bytes as bus width for Stoney.
