6.6-stable review patch. If anyone has any objections, please let me know.

From: Evgeny Pimenov pimenoveu12@gmail.com
commit a31a4934b31faea76e735bab17e63d02fcd8e029 upstream.
Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()).
Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
