ChibiOS Consolidation

[tzarc]

• Refactor ChibiOS board file support so keyboards don't need full chconf.h/halconf.h/mcuconf.h/board.c/board.h files
• Refactor board definitions to point to ChibiOS files instead of providing our own board.c/board.h
• Refactor existing keyboards to use new board definitions
• Refactor existing keyboards to either remove or refactor conf files based on what they need
• Refactor existing keyboards to use early init functions instead of __early_init and boardInit
• Add EARLY_INIT_PERFORM_BOOTLOADER_JUMP TRUE to all boards that use the ST bootloader
• Invert logic of EARLY_INIT_PERFORM_BOOTLOADER_JUMP so that it's opt-out instead of opt-in
  • Fixup bootloader entry documentation to remove note about F042 (should work after this change)
  • Update documentation here
• Remove EARLY_INIT_PERFORM_BOOTLOADER_JUMP from keyboards that don't need it after the logic inversion
• Add documentation on how to override specific entries in conf files
