On downstream the panel uses a regulator and an enable pin, but it is hinted
that the enable pin is actually another regulator, so wrap the enable pin into
a regulator and put the two new regulator in the panel node.

[PATCH v5 4/4] ARM: dts: qcom: msm8974-klte: Mark essential regulators

[Iskren Chernev]

s1 and l12 regulators are used for the memory and cache on the Samsung
S5 (klte). If they are turned off the phone shuts down. So mark them as
always-on to prevent that from happening.
