ASoC: rt5645: Make LattePanda board DMI match more precise 

The DMI strings used for the LattePanda board DMI quirks are very generic.

Using the dmidecode database from https://linux-hardware.org/ shows
that the chosen DMI strings also match the following 2 laptops
which also have a rt5645 codec:

Insignia NS-P11W7100 https://linux-hardware.org/?computer=E092FFF8BA04
Insignia NS-P10W8100 https://linux-hardware.org/?computer=AFB6C0BF7934

All 4 hw revisions of the LattePanda board have "S70CR" in their BIOS
version DMI strings:

DF-BI-7-S70CR100-*
DF-BI-7-S70CR110-*
DF-BI-7-S70CR200-*
LP-BS-7-S70CR700-*

See e.g. https://linux-hardware.org/?computer=D98250A817C0



Add a partial (non exact) DMI match on this string to make the LattePanda
board DMI match more precise to avoid false-positive matches.
