samd: Integrate latest asf4, add help, more time funcs and uPy features.
- Makefile: update to use new ASF4 files, support frozen manifest, and include source files in upcoming commits - boards/manifest.py: add files to freeze - boards/samd51p19a.ld: add linker script for this MCU - help.c: add custom help text - main.c: execute _boot.py, boot.py and main.py on start-up - modules/_boot.py: startup file to freeze - modutime.c: add gmtime, localtime, mktime, time functions - mpconfigport.h: enabled more features for sys and io and modules - mphalport.h: add mp_hal_pin_xxx macros - mphalport.c: add mp_hal_stdio_poll
