ARM: dts: configure regulators for Gumstix Pepper
Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.
The consumers of the regulators this commit affect are the followings:
DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
DCDC2: Core domain
DCDC3: MPU core domain
LDO1: RTC
LDO2: 3v3 IO domain
LDO3: USB-PHY; not a boot-time requirement
LDO4: LCD [16:23]
All but LDO3 need to be always-on for the system to be functional.
Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.
