[SC64][FW][SW] Controller rewrite to remove task subsystem + minor bug fixes (#64)
This PR completely removes `task.c / task.h` from `sw/controller` STM32
code.
Additionally, these changes were implemented:
- Updated IPL3
- Added new diagnostic data (voltage and temperature) readout commands
for USB and N64
- Fixed some issues with FlashRAM save type
- Joybus timings were relaxed to accommodate communication with
unsynchronized master controller (like _Datel Game Killer_, thanks
@RWeick)
- N64 embedded test program now waits for release of button press to
proceed
- Fixed issue where, in rare circumstances, I2C peripheral in STM32
would get locked-up on power-up
- LED blinking behavior on SD card access was changed
- LED blink duration on save writeback has been extended
- Minor fixes through the entire of hardware abstraction layer for STM32
code
- Primer now correctly detects issues with I2C bus during first time
programming
- `primer.py` script gives more meaningful error messages
- Fixed bug where RTC time was always written on N64FlashcartMenu boot
- sc64deployer now displays "Diagnostic data" instead of "MCU stack
usage"
