Subject: [PATCH 1/6] ASoC: qcom: x1e80100: set card driver name from match data

Sound machine drivers for Qualcomm SoCs can be reused across multiple
SoCs. But user space ALSA UCM files depend on the card driver name which
should be set per board/SoC.

Allow such customization by using driver match data as sound card driver
name.
