Subject: [PATCH] arm64: dts: rockchip: rock-3a: Remove bluetooth node

From: Chen-Yu Tsai <wens@...e.org>

The Bluetooth node described in the device tree is actually on an M.2
slot. What module is present depends on what the end user installed,
and should be left to an overlay.

Remove the existing bluetooth node. This gets rid of bogus timeout
errors.

Fixes: 8cf890aabd45 ("arm64: dts: rockchip: Add nodes for SDIO/UART Wi-Fi/Bluetooth modules to Radxa Rock 3A")
