This adds the minimal get_time/set_time support for the rp2040 and
enables support by default on the Pico boards. This doesn't support
configuring the clock source or alarm interrupts yet.

The number of IRQ priority bits was incorrectly set to 3 instead
of 2, which is the correct number for Cortex-M0+.

Added a generic driver for RaspberryPi Pico PIO.
This driver is an intermediate driver for abstracting the PIO
device driver from physical pin configuration.

The addresses of the flash and flash controller of the RP2040
SoC were mixed up. There was no clear distinction between the
flash and the flash controller, which was unclear but also
caused a DTC warning.
This commit makes the distinction clearer: The SSI peripheral at
0x18000000 is the flash controller, and the flash itself starts
at 0x10000000. The flash driver and rpi_pico.dts were fixed
accordingly.

The pinctrl node of the RP2040 had the same unit address as the GPIO
bank, causing a DTC warning. To fix this, the pinctrl's address was
removed, as it does not require any.

Define RaspberryPi Pico ADC.
The ADC has internally connected temperature sensor,
Add property to enable this.
The ADC has a single VREF. VCC usually connects to it,
but it may not be in a case.
Add property to make configurable it.

Add spi0 and spi1 configuration to rp2040.
spi0 and spi1 are declared as compatible with
"raspberrypi,pico-spi" and "arm,pl022".
"raspberrypi,pico-spi" is just inherited from
"arm,pl022" and "reset-device"
spi0 and spi1 declare as compatible with "raspberrypi,pico-spi"
and "arm,pl022".
"raspberrypi,pico-spi" is just inheriting "arm,pl022" and
"reset-device" for declaring the 'reset' property,
with no additional property and implementation.
Add also pinctrl macros to dt-bindings header.

In order to bring consistency in-tree, migrate all dts code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.
