Subject: [PATCH] ARM: dts: qcom: keep L2F and L3F regulators always-on for Sun
 boards

Configure the L2F and L3F regulators on Sun boards to be always
enabled.  This ensures that WCN hardware operates correctly.
Use low power mode (LPM) as the initial mode to reduce current
consumption before BT or WLAN is enabled.
