USB vbus 5V is from PMIC SWBST, so set swbst_reg as vbus's
parent reg, it fixed a bug that the voltage of vbus is incorrect
due to swbst_reg is disabled after boots up.

All chips of i.mx6 can be powered off by programming SNVS.
For example :
On i.mx6q-sabresd board, PMIC_ON_REQ connect with external
pmic ON/OFF pin, that will cause the whole PMIC powered off
except VSNVS. And system can restart once PMIC_ON_REQ goes
high by push POWRER key.

The lcdif node has a property named "display" and also a child node
called "display", which causes the following warning:

device-tree: Duplicate name in lcdif@02220000, renamed to "display#1"

Rename the child node name in order to avoid the warning.

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.

With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.

In case the bootloader has incorrectly configured the ALT mode of
MX6SL_PAD_ECSPI1_SS0 pad, we end up with the following probe error:

m25p80 spi0.0: found mr25h256, expected m25p32
m25p80 spi0.0: mr25h256 (32 Kbytes)

In order to avoid this issue, add an entry for MX6SL_PAD_ECSPI1_SS0 pad, so
that kernel configures the ECSPI chip select as GPIO functionality, which
results in correct SPI NOR probe.

On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the
imx6sl SoC, so we need to keep it always powered.

According to imx6sl datasheet the GPIO block has three supplies:
NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that:
"All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions
whether the associated I/O pins are in use or not"

This problem has been observed by the fact that a GPIO connected to an LED could
not work when the PMIC driver was enabled.

Keeping VGEN1 regulator always enabled fixes the problem.

The device tree specification recommends that generic name should be
used for nodes.  So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

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.
