Infinix ZERO BOOK 13 has a 2+2 speaker system which isn't probed correctly. This patch adds a quirk with the proper pin connections. Also The mic in this laptop suffers too high gain resulting in mostly fan noise being recorded, This patch Also limit mic boost.

HW Probe for device; https://linux-hardware.org/?probe=a2e892c47b

Test: All 4 speaker works, Mic has low noise. Signed-off-by: Piyush Raj Chouhan piyushchouhan1598@gmail.com
