Add device managed APIs devm_pinctrl_register() and

and pinctrl_unregister().

This helps in reducing code in error path and sometimes
removal of .remove callback for driver unbind.

Parking bits might not be cleared by the bootloader properly (if for
instance it doesn't use the device configured by that pin). Clear
the park bits for all the pins during pinctrl probe.

This is present on T210 platforms but not earlier ones, so for earlier
generations, set parked_reg = -1 to disable.

The park bit is used to prevent glitching when reprogramming pinctrl
registers.

This patch adds the get_direction to support the gpio
interface.

The gpio direction is not used on rockchip platform when use the gpio
debugfs.

Tested on kylin board. (RK3036 SoCs)
The repro steps:
$/sys/class/gpio/
echo 53 > export
$/sys/class/gpio/gpio53# cat direction
in
In general, the gpio53 should be out value, but the direction is the
default value 'in',  since the get_direction didn't supported in rockchip
pinctrl.

So, we should add this patch to support it.
