Add CX9020 board based on mx53loco.
Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse
serial_mxc with DTE and prepare for device tree migration of other
functions and imx53 devices.
The CX9020 differs from i.MX53 Quick Start Board by:
- use uart2 instead of uart1
- DVI-D connector instead of VGA
- no audio
- CCAT FPGA connected to emi
- enable rtc

There two iomuxc for i.MX6SLL. One is normal IOMUXC, the other
is for IOMUXC_SNVS.

It is not usual that drivers announce when they have been initialized.
use dev_dbg to announce device initialization.

There two iomuxc for i.MX6ULL. one iomuxc is compatible is i.MX6UL,
the other iomuxc is for SVNS usage, similar with the one in mx7.

Introudce i.MX7 pinctrl driver support.
For now only i.MX7D supported.
There are two iomux controllers in i.MX7D, iomuxc and iomuxc_lpsr.
To iomuxc_lpsr, ZERO_OFFSET_VALID is set, means offset of mux_reg
and conf_reg can begin at 0.

Introduce pinctrl for i.MX6
1. pinctrl-imx.c is for common usage. It's used by i.MX6/7.
2. Add PINCTRL_IMX PINCTRL_IMX6 Kconfig entry.
3. To the pinctrl_ops implementation, only set_state is implemented.
To i.MX6/7, the pinctrl dts entry is as following:
&iomuxc {
pinctrl-names = "default";
pinctrl_csi1: csi1grp {
fsl,pins = <
MX6UL_PAD_CSI_MCLK__CSI_MCLK 0x1b088
MX6UL_PAD_CSI_PIXCLK__CSI_PIXCLK 0x1b088
MX6UL_PAD_CSI_VSYNC__CSI_VSYNC 0x1b088
>;
};
[.....]
};
there is no property named function or groups. So pinctrl_generic_set_state
can not be used here.
5. This driver is a simple implementation for i.mx iomux controller,
only parse the fsl,pins property and write value to registers.
6. With DEBUG enabled, we can see log when "i2c bus 0":
"
set_state_simple op missing
imx_pinctrl_set_state: i2c1grp
mux_reg 0x14c, conf_reg 0x3bc, input_reg 0x5d8, mux_mode 0x0, input_val 0x1, config_val 0x4000007f
write mux: offset 0x14c val 0x10
select_input: offset 0x5d8 val 0x1
write config: offset 0x3bc val 0x7f
mux_reg 0x148, conf_reg 0x3b8, input_reg 0x5d4, mux_mode 0x0, input_val 0x1, config_val 0x4000007f
write mux: offset 0x148 val 0x10
select_input: offset 0x5d4 val 0x1
write config: offset 0x3b8 val 0x7f
"
this means imx6 pinctrl driver works as expected.
