[PATCH] ASoC: amd: acp: Fix incorrect retrival of acp_chip_info

[Venkata Prasad Potturu <venkataprasad.potturu@amd.com>]

Use dev_get_drvdata(dev->parent) instead of dev_get_platdata(dev)
to correctly get acp_chip_info members in acp I2S driver.
This resolves issues where some members were zero due to incorrect
data access.

Fixes: e3933683b25e ("ASoC: amd: acp: Remove redundant acp_dev_data structure")
