[PATCH 044/379][SRU][OEM-5.6] ath11k: add handling for BSS color

[You-Sheng Yang]

From: John Crispin <john at phrozen.org>

BugLink: https://bugs.launchpad.net/bugs/1879633

This patch adds code to handle the BSS_CHANGED_BSS_COLOR flag. It will
trigger the propagation of BSS color settings into the FW. Handling is
slightly different between AP and STA interfaces.
