boards: Board definition for the Raspberry Pi Pico W.
Effort has been made to abstract the features that are common to both the Pico and Pico W into a shared file when possible. This commit does not include the addition of bluetooth or wifi drivers for the W's Infineon module. Signed-off-by: Dave Rensberger <[email protected]>

the datasheet to see the possible routings for each peripheral.

External pin mapping on the Pico W is identical to the Pico, but note that internal

RP2040 GPIO lines 23, 24, 25, and 29 are routed to the Infineon module on the W.

Since GPIO 25 is routed to the on-board LED on the Pico, but to the Infineon module

on the Pico W, the "blinky" sample program does not work on the W (use hello_world for

a simple test program instead).
