This reverts commit 59df934af7 which was
comit e153db03c6b7a035c797bcdf35262586f003ee93 upstream.
It requires a driver that was not merged until 4.16, so remove it from
this stable tree as it is pointless.

[ Upstream commit e153db03c6b7a035c797bcdf35262586f003ee93 ]
The correct DT property for specifying a GPIO used for reset
is "reset-gpios", fix this here.

Audio-in was incorrectly routed to Line In. It should be Mic3L as per
schematic.
Using mic-bias voltage at 2.0v (<0x1>) does not work for some reason. There
is no voltage seen on micbias (R127). Mic-bias voltage of 2.5v (<0x2>) works.
I see voltage of 2.475v across GND and micbias.
With these changes, I can record audio with a pair of proliferate TRRS earbuds.

The device tree for Gumstix Pepper has DCDC2 and
DCDC3 correctly labelled but the upper limit values
are wrong. The confusion is due to the hardware
quirk where the DCDC2 and DCDC3 wires are flipped
in 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.
