Instead of calling the regulator for the ARM core as 'cpu', let's rename it
as 'vddarm', so that we keep a better consistency with the other internal
regulators:

vdd1p1: 800 <--> 1375 mV at 1100 mV
vdd3p0: 2800 <--> 3150 mV at 3000 mV
vdd2p5: 2000 <--> 2750 mV at 2400 mV
vddarm: 725 <--> 1450 mV at 1150 mV
vddpu: 725 <--> 1450 mV at 1150 mV
vddsoc: 725 <--> 1450 mV at 1200 mV

This makes the structure of Sabre Lite board files the same
as Sabre SD board files so that they are easier to compare.

and imx6dl-sabrelite.dts can include it.

We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.

This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.
