[PATCH 07/15] staging: rtl8723bs: remove unused code blocks conditioned by never set CONFIG_BACKGROUND_NOISE_MONITOR

From: Fabio Aiuto
Date: Mon Mar 15 2021 - 06:16:45 EST

remove conditional code blocks checked by unused
CONFIG_BACKGROUND_NOISE_MONITOR

cleaning required in TODO file:

find and remove code blocks guarded by never set CONFIG_FOO defines
