dt-bindings: regulator/mfd: Reorganize S5M8767 bindings

The regulator/s5m8767-regulator.txt duplicates some of the information
about bindings with old mfd/s2mps11.txt. Now common part exists entirely
in mfd/samsung,sec-core.txt so:
 - add company prefix to file name (regulator/samsung,s5m8767.txt),
 - remove duplicated information,
 - reorganize the contents to match style of
   regulator/samsung,s2mps11.txt.

-* Samsung S5M8767 Voltage and Current Regulator
+Binding for Samsung S5M8767 regulator block
+===========================================
 
-The Samsung S5M8767 is a multi-function device which includes voltage and
-current regulators, rtc, charger controller and other sub-blocks. It is
-interfaced to the host controller using a i2c interface. Each sub-block is
-addressed by the host system using different i2c slave address. This document
-describes the bindings for 'pmic' sub-block of s5m8767.
