Fix incorrect printf format specifier

1

PRI macros should be used for uintptr_t. Calling a printf-like function with the wrong type of arguments causes unpredictable behavior.

As stated in [README.md](https://github.com/raspberrypi/pico-sdk/tree/master/src/rp2_common#readme), hardware_* are Hardware Abstraction Layer (HAL), while pico_* provide higher level functionality. I have noticed that some code in pico_* accesses memory-mapped I/O (MMIO) without going...
