NVIDIA's Tegra210 support the park bit to make pinmux configuration
enable/disable. If parked bit is 1 then configuration does not apply
and if it is 0 then pinmux configuration applies. This is to support
to avoid any glitch in pinmux configurations.
The parked bit is part of mux register and mux bank and hence it is
not required to have member for the parked_reg and parked bank very
similar to other bit field of the same register.
Remove the need of the parked register and parked bank and get whether
parked function supported or not by parked_bit.
This is to make the parked bit handling same as other fields of mux
registers.

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.

Tegra has several pinctrl drivers. Now it is reasonable enough to
move them into drivers/pinctrl/tegra/.
