pinctrl_gpio_direction_input() now has the same signature as the
wrapper around it so we can drop them.

Now that pinctrl_gpio_direction_output() is no longer used, let's drop
the '_new' suffix from its improved variant.

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

Add support for rk806 dvs pinctrl to the existing rk805
driver.
This has been implemented using shengfei Xu's rk806
specific driver from the vendor tree as reference.

When creating MFD platform devices the firmware node is left unset.
This, in particular, prevents GPIO library to use it for different
purposes. Propagate firmware node from the parent device and let
GPIO library do the right thing.
While at it, slightly modify the headers to reflect the usage of APIs.

Mark pin_cfg as const, allowing the compiler to put the struct in
.rodata instead of .data.

Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0.
Main benefit is to make it easier to see which values mean IN and which
OUT. As a side effect this helps GPIO framework to change the direction
defines to something else if ever needed.
Please note that return value from get_direction call on
pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have
returned value 2 for direction INPUT.

Static structures rk805_pinctrl_desc and rk805_gpio_chip, of types
gpio_chip and pinctrl_desc respectively, are not used except to be
copied into the fields of a different variable. Hence make
rk805_pinctrl_desc and rk805_gpio_chip both constant to protect them
from unintended modification.
Issue found with Coccinelle.

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.
