Implement i2c_idle_bus in driver, then setup_i2c can
be dropped for boards which enable DM_I2C/DM_GPIO/PINCTRL.
The i2c_idle_bus force bus idle flow follows setup_i2c in
arch/arm/imx-common/i2c-mxv7.c
This patch is an implementation following linux kernel patch:

commit 1c4b6c3bcf30d0804db0d0647d8ebeb862c6f7e5

i2c: imx: implement bus recovery
Implement bus recovery methods for i2c-imx so we can recover from
situations where SCL/SDA are stuck low.
Once i2c bus SCL/SDA are stuck low during transfer, config the i2c
pinctrl to gpio mode by calling pinctrl sleep set function, and then
use GPIO to emulate the i2c protocol to send nine dummy clock to recover
i2c device. After recovery, set i2c pinctrl to default group setting.
"
See Documentation/devicetree/bindings/i2c/i2c-imx.txt for detailed
description.
1. Introuduce scl_gpio/sda_gpio/bus in mxc_i2c_bus.
2. Discard the __weak attribute for i2c_idle_bus and implement it,
since we have pinctrl driver/driver model gpio driver. We can
use device tree, but not let board code to do this.
3. gpio state for mxc_i2c is not a must, but it is recommended. If
there is no gpio state, driver will give tips, but not fail.
4. The i2c controller was first probed, default pinctrl state will
be used, so when need to use gpio function, need to do
"pinctrl_select_state(dev, "gpio")" and after force bus idle,
need to switch back "pinctrl_select_state(dev, "default")".
This is example about how to use the gpio force bus
idle function:
"
&i2c1 {
clock-frequency = <100000>;
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_i2c1>;
pinctrl-1 = <&pinctrl_i2c1_gpio>;
scl-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
sda-gpios = <&gpio1 29 GPIO_ACTIVE_HIGH>;
status = "okay";
[....]
};
[.....]
pinctrl_i2c1_gpio: i2c1grp_gpio {
fsl,pins = <
MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x1b8b0
MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x1b8b0
>;
};

The description was borrowed from kernel. "tristate" type was changed
to "bool" (I believe we don't support modules for u-boot yet, right?).
CONFIG_USB_GADGET requires CONFIG_USB to be defined too, so add it along
as well.
Definitions were added to defconfig files in a way that
"make savedefconfig" generates exactly the same file as used defconfig.

The behavior before this patch would attempt to configure the mux
setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS. The
LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27
as in the parallel LCD interface. This patch restricts the
configuration to only the relevant pins 18 to 27 on PORTD.
This was tested on a sun8i A33 tablet with an LVDS screen. MMC1 has
the capability to use pins 2 to 7 on PORTD and the mux on those pins
was being inadvertently set to setting 3 for MMC functionality which
this patch corrects.

For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

For Raspberry Pi, we had the input clock rate to the pl011 fixed in
the rpi.c file, but it may be changed by firmware due to user changes
to config.txt. Since the firmware always sets up the uart (default
115200 output unless the user changes it), we can just skip our own
uart init to simplify the boot process and more reliably get serial
output.

When 'usb start' is used, block devices are created for any USB flash sticks
and disks, etc. When 'usb stop' is used, these block devices are currently
not removed.
We don't want old block devices hanging around since they can still be
visible to U-Boot. Therefore, when USB is shut down, remove and unbind all
the block devices created by the USB subsystem.
Possibly we should unbind all devices which don't cause problems by being
unbound. Most likely we can remove everything except USB controllers, hubs
and emulators. We can consider that later.

This driver supports VESA as the mode-setting mechanism. Since most boards
