FROMLIST: usb: Migrate to support live DT for some driver

Use ofnode_ instead of fdt_ APIs so that the drivers can support live DT.
This patch updates usb_get_dr_mode() and usb_get_maximum_speed() to use
ofnode as parameter instead of fdt offset. And all the drivers who use
these APIs update to use live dt APIs at the same time.

UPSTREAM: stm32mp1: add stusb1600 support for DK1 and DK2 board

The DK1 and DK2 boards use the USB Type-C controller STUSB1600.
This patch updates:
- the device tree to add the I2C node in the DT
- the board stm32mp1 to probe this I2C device and use this controller
to check cable detection.
- the DWC2 driver to support a new dt property
"u-boot,force-b-session-valid" which forces B session and
device mode; it is a workaround because the VBUS sensing and
ID detection isn't available with stusb1600.

tx_fifo_sz_array[] is 17 Bytes long and can contains max 16
tx fifo size (synopsys IP supports max 16 IN endpoints).
First entry of tx_fifo_sz_array[] is the number of valid
fifo size the array contains.

number of element than max hardware endpoint, display
a warning message.

Compatibility with board which doesn't use tx_fifo_sz_array[]

treewide: replace with error() with pr_err()

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

# define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

usb: gadget: dwc2: avoid reset core before devices connected

Theoretically, the UDC register need not reconfig when GINTSTS.USBRst
is set, and only do core reset if the devices was connected before.
This change adds _connected_ flag to check the devices was really
connected or not. As an optimization, reset device address to zero
while GINTSTS.USBRst is set.

This patch fix usb connect failed when continuously perform the
'fastboot reboot-bootloader' command.
