Subject: [PATCH] arm64: dts: qcom: sdm630-nile: Enable and configure PM660L
 WLED

The board-specific (electrical) configuration was removed from PM660L in
90ba636e40cb ("arm64: dts: qcom: pm660l: Remove board-specific WLED
configuration") as it is platform-dependent.  We reintroduce it here in
the Nile board configuration (with a slightly lower current limit, as
per downstream DT sources) and enable it for use in the dsi0 node.
