mwifiex: control WLAN and bluetooth coexistence modes
By default our chip will be in spatial coexistence mode.
This patch adds a provision to change it to timeshare mode
via debugfs command.
Enable timeshare coexistence mode
echo 1 > /sys/kernel/debug/mwifiex/mlan0/timeshare_coex
Go back to spacial coexistence mode
echo 0 > /sys/kernel/debug/mwifiex/mlan0/timeshare_coex
