Prior to this commit, Pin(Pin.OPEN_DRAIN, value=0) would not set the
initial value of the open-drain pin to low, instead it would be high.

When switching from a special function like SPI to an input or output,
there was a brief period after the function was disabled but before the
pin's I/O state was configured, in which the state would be poorly defined.
This fixes the problem by switching off the special function after fully
configuring the I/O state.
Fixes#10226.

If USB CDC is connected and the board sends data, but the host does not
receive the data, the device locks up. This is fixed in this commit by
having a timeout of 500ms, after which time the transmission is skipped.
Fixes issue #9634.
This includes:
- Configuration file for the cyw43-driver.
- Integration of cyw43-driver into the build, using lwIP.
- Enhancements to machine.Pin to support extension IO pins provided by the
CYW43xx.
- More mp-hal pin helper functions.
- mp_hal_get_mac_ascii MAC address helper function.
- Addition of rp2.country() function to set the country code.
A board can enable this driver by setting MICROPY_PY_NETWORK_CYW43 in their
cmake snippet.
Work done in collaboration with Graham Sanderson and Peter Harper.

This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.
The build system uses pure cmake (with a small Makefile wrapper for
convenience). The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented. Some examples are provided
in the examples/rp2/ directory.
Work done in collaboration with Graham Sanderson.
