TI Palmas series Power Management IC have multiple pins which can be
configured for different functionality. This pins can be configured
for different function. Also their properties like pull up/down,
open drain enable/disable are configurable.

Add support for pincontrol driver Palmas series device like TPS65913,
TPS80036. The driver supports to be register from DT only.

Changes from V1:
- Add generic property for pins and functions in pinconf-generic.
- Add APIs to map the DT and subnode.
- Move common utils APIs to the pinctrl-utils from this file.
- Update the binding document accordingly.
Changes from V2:
- Add ack by Lee.
- Correct the binding docs.

Some of pincontrol driver needs the utility function to create map
list. The utility function needed for adding mux, configs etc.

In place of duplicating this in each driver, add the common utility
function in common file and use from device specific driver. This will
reduce the duplicating of code across drivers.

Changes from V1:
- Add this files in this patch and add common utility APIs to here.

Changes from V2:
- Nothing in code.
- Added Reviewed by Stephen.

One peripheral may share part of its pins with the 2nd
peripheral and the other pins with the 3rd. If it requests all pins
when part of them has already be requested and owned by the 2nd
peripheral, this request fails and pinmux_disable_setting() is called.
The pinmux_disable_setting() frees all pins of the first peripheral
without checking if the pin is owned by itself or the 2nd, which
results in the malfunction of the 2nd peripheral driver.

The current implementation handle both edge and level interrupts with the
'handle_simple_irq' handler.

Level interrupts are active as long as the pin stays at the configured
level (low or high). In this case we have to use 'handle_level_irq' which
mask the interrupt until the handle has treated it.

The select input for some pin may not be implemented using the regular
select input register but the general purpose register.  A real example
is that imx6q designers found the select input for USB OTG ID pin is
missing at the very late stage, and can not add a new select input
register but have to use a general purpose register bit to implement it.

The patch adds a workaround for such select input quirk by interpreting
the input_val cell of pin function ID in a different way, so that all
the info that needed for setting up select input bits in general purpose
register could be decoded from there.

So, I notice that we get a couple of warnings from the pinctrl code:

drivers/pinctrl/pinconf.c: In function 'pinconf_dbg_config_print':
drivers/pinctrl/pinconf.c:433:36: warning: 'configs' may be used uninitialized in this function
drivers/pinctrl/pinconf.c: In function 'pinconf_dbg_config_write':
drivers/pinctrl/pinconf.c:511:36: warning: 'configs' may be used uninitialized in this function

While the compiler might not be able to work out that "configs" is
safe, the code doesn't lend itself very well to identifying that
fact when reading it either.  This can be trivially solved by a slight
restructuring of the code - which also reduces the LOC.
