Add a new reset driver for GD32 platforms. This driver controls the
reset registers from the RCU peripheral. It can be used to restore
peripherals to their initial state when initializing a device.

It was not possible to disconnect a pin using the nRF pinctrl driver.
That is, it was not possible to set PSEL to 0xFFFFFFFF (indicating pin
is not connected). This can be useful in certain scenarios, e.g. a
bootloader configures all signals of a certain peripheral but
application then needs to disconnect certain signals.
A new DT macro has been introduced to accomplish this:
NRF_PSEL_DISCONNECT. It can be used like this to explicitely disconnect
a peripheral signal:
```
&pinctrl {
uart0_default: uart0_default {
group1 {
psels = <NRF_PSEL(UART_TX, 0, 1)>,
<NRF_PSEL_DISCONNECTED(UART_RX)>;
};
};
};
```

This commit enables the SoC's flash memory controller.
- added lpc55s36 specific code in the NXP MCUX driver
to take advantage of the SoC's check-before-read
capability
- enabled the FMC node in the SoC's dtsi (iap)
- added the flash controller chosen node to the board's dts

Disable flexspi flash controller by default, allow boards to enable it.
This SOC uses external flash, so boards should only enable the flash
controller when their specific flash module has been verified to work

According to DT spec, device_type property is deprecated (ref. 0.3 spec,
2.3.11):
> The device_type property was used in IEEE 1275 to describe the device’s
FCode programming model. Because DTSpec does not have FCode, new use
of the property is deprecated, and it should be included only on cpu and
memory nodes for compatibility with IEEE 1275–derived devicetrees.

Add the support of the temperature sensor in the ADC device-tree node of
each stm32 where it is available.
- Check all the ADC of the stm32 mcus where the temp and VrefInt monitoring
is available (based on the Ref Man).
- Check that has-temp-channel; and has-vref-channel; in the corresponding
ADC node of the DTS of each stm32 mcu is correctly set.
- Verify the VTEMP/ VREFINT activation in the in adc_stm32.c for example).

Remove 'ranges' property from gpio node as it shouldn't be there
since we aren't converting 1:1 between address spaces. This fixes

We currently get a number of warnings like:
Warning (simple_bus_reg): /soc/otgfs_phy: missing or empty
reg/ranges property
This is due to the usb phy nodes not have a reg property since they
don't have an mmio address associated with them.
Move the phy nodes out of the SoC node so their lack of a reg property
will not cause a warning. This is similar to how Linux dts files
handle the phy nodes.

Adding I2C FIFO mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.
The I2C master supports two 32-bytes FIFOs, channel A and C
are supported now.
I2C FIFO mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.52ms(2.4ms->1.88ms) compared to the original pio mode when the
frequency is 100KHz.
3. It is normal to read sensor data through I2C on Nereid's platform.
