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. The QRB4210 RB2 gets its name set to "sm4250" as requested by
Srinivas Kandagatla, and since no (known) UCM has been written yet this
should not break anything.

Also while we're already touching these lines, sort the compatibles
alphabetically.
