Subject: [PATCH] ASoC: max98383: add  88200 and 96000 sampling rate support

From: fengchunguo <chunguo.feng@...ogic.com>

88200 and 96000 sampling rate was not enabled on driver, so can't be played.

The error information:
max98373 3-0031：rate 96000 not supported
max98373 3-0031：ASoC: can't set max98373-aif1 hw params: -22
