The reset function should reset cycle a single subsystem. Therefore it
should not assume every reset of each subsystem is deasserted, when
calling this function. Additionally add some comments for the intent of
the function itself.

The examples have been moved into a seperate repository. Other
controller specific repositories do not contain a copy of the examples.
The examples could be found in the folder raspberrypi-rp2040
within the repository ZigEmbeddedGroup/microzig-examples.

* support for a subset of the bootrom functions added: fast bit count/ manipulation functions (tested), fast bulk memory fill/ copy functions (tested), flash access functions (NOT tested), debugging support functions (not implemented), miscellaneous functions (not implemented).
* added support for erasing and programming flash from user code. between the first and last call in a programming sequence, the SSI is not in a state where it can handle XIP accesses, so the code that calls the intervening functions must be located in SRAM. this is why I added the time_critical section to rp2040.ld (maybe one should create a dedicated section in ram that is rwx and keep data rwNx).
* flash_program.zig example added
