Add support for probing the pinctrl-ingenic driver on the
JZ4730 SoC from Ingenic.

This driver is derived from Paul Boddie. It is worth to
noting that the JZ4730 SoC is special in having two control
registers (upper/lower), so add code to handle the JZ4730
specific register offsets and some register pairs which have
2 bits for each GPIO pin.

1.In the JZ4740 part, remove pointless "lcd-no-pins", use "lcd-special"
  and "lcd-generic" instead "lcd-18bit-tft". Currently, in the mainline,
  no other devicetree out there is using the "lcd-18bit-tft" ABI, so we
  should be able to replace it safely.
2.In the JZ4725B part, adjust the location of the LCD pins related code
  to keep them consistent with the style of other parts.
3.In the JZ4760 part, add the missing comma and adjust element order in
  "jz4760_lcd_special_pins[]", keep them in the order of CLS/SPL/PS/REV
  like other "lcd_special_pins" arrays. And adjust the location of the
  "jz4760_lcd_generic" related code to keep them consistent with the
  style of other parts.
4.In the JZ4770 part, remove pointless "lcd-no-pins", add the missing
  "lcd-16bit", "lcd-18bit", "lcd-special", "lcd-generic".
5.In the X1000 part and the X1500 part, remove pointless "lcd-no-pins".
6.In the X1830 part, replace "lcd-rgb-18bit" with "lcd-tft-8bit" and
  "lcd-tft-24bit", because of the description of the TRANS_CONFIG.MODE
  register bits in the PM manual of the X1830, shows that the X1830 only
  supppots 24bit mode and 8bit mode for tft interface, only 18 pins in
  the GPIO table are because of the data[17:16], the data[9:8], and the
  data[1:0] has not been connected. And according to the description,
  the two interfaces supported by X1830 are respectively referred to as
  "TFT interface" and "SLCD interface", so the "lcd-rgb-xxx" is replaced
  with "lcd-tft-xxx" to avoid confusion.

The slew rate was enabled by default for each configuration of the
pin. In case the pin had more than one configuration, even if
we set the slew rate as disabled in the device tree, the next pin
configuration would set again the slew rate enabled by default,
overwriting the slew rate disablement.
Instead of enabling the slew rate by default for each pin configuration,
enable the slew rate by default just once per pin, regardless of the
number of configurations. This way the slew rate disablement will also
work for cases where pins have multiple configurations.

The Special Function Registers on all Exynos SoC, including ARM64, are
32-bit wide, so entire driver uses matching functions like readl() or
writel().  On 64-bit ARM using unsigned long for register masks:
1. makes little sense as immediately after bitwise operation it will be
   cast to 32-bit value when calling writel(),
2. is actually error-prone because it might promote other operands to
   64-bit.
