Subject: [PATCH 1/2] ASoC: max98090: Add max98091 compatible string

From: Wonjoon Lee <woojoo.lee@...sung.com>

The MAX98091 CODEC is the same as MAX98090 CODEC, but with an extra
microphone. Existing driver for MAX98090 CODEC already has support
for MAX98091 CODEC. Adding proper compatible string so that MAX98091
CODEC can be specified from device tree.
