Purdea Andrei 38f554ef4f drivers: gpio_rpi_pico.c: add support for single-ended IO
Note: RP2040 can support single-ended IO, by setting the GPIO_OUT
register to a constant value, and then changing the GPIO_OE register
instead, when the output has to change. To do this, the output-setting
functions need to know which pins have been configured as single-ended,
and for that reason the data structure has been extended to include
this information.

Another change is the PR, is that setting of the pull-ups/pull-downs
now applies to both inputs and outputs as well. Previous solution was
wrong, because if the user wanted to set up an input with a pull
resistor enabled, and then reconfigure it to an output without any
pulls, then the pulls remained in place for the output. Now pulls
are correctly set based on the gpio flags for outputs too, and this
is especially useful for single-ended outputs too.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
