\brief Raspberry Pi Pico and Pico W driver

This driver is known to work with the following MCUs:
- Raspberry Pi Pico W

\note While the RP2040's datasheet claims it supports multi-master
configurations by implementing bus arbitration, it does not natively support
a mode where it is configured as a (multi-)master with a slave address, such
that it can be addressed by other multi-masters.

\note This driver includes a workaround that uses both I2C peripherals on the
RP2040. To use this driver, make sure you initialize both I2C peripherals, and
connect their respective SDA and SCL pins to the same I2C bus.

\par Usage
- Link the \c pbdrv-mod library with your main executable
- Call the \c pb_setup() function (from \c <pb-mod.h>) during setup

\note This driver is automatically enabled if the variable \c PICO_PLATFORM is
equal to \c "rp2040" in your CMakeLists.txt (it is by default when using the
pico-sdk CMake library).

\note This driver automatically includes the \ref pb_ext_stdlib
"stdlib extension" as the pico-sdk implements the C standard library.
