Since btcoex enabled by default in firmware, host needs to enable COEX support depends on the hardware. Enabling it by default in unsupported hardware will cause some feature disabled in hardware. This patch will read btcoex_support flag and wlan priority gpio pin number from DT. Depends on the btcoex_support flag value host will expose BTCOEX support and wlan priority gpio pin number to target.
