[PATCH] arm64: dts: amlogic: meson-gxl-s905d-phicomm-n1: add bluetooth node

[Jun Yan]

The Phicomm N1 uses a CY43455 (BCM43438) module with its Bluetooth
interface connected to uart_A.

Add the required device tree node to enable proper functionality.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v7.1/arm64-dt)

[1/1] arm64: dts: amlogic: meson-gxl-s905d-phicomm-n1: add bluetooth node
      https://git.kernel.org/amlogic/c/d6df314c0165cb809d6c647a593664a4f5028230

These changes has been applied on the intermediate git tree [1].

The v7.1/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
