[REFACTOR] Extract peripheral initialisations to relevant drivers

Summary

Currently, many of the STM32 peripherals initialisation code (e.g. GPIO bringup, peripheral config) are isolated in monolithic functions that bring-up all used ports in one go. This refactor aims to extract individual initialisations to the relevant drivers of the devices that require it.

Detailed Description

Current problem areas for initialisation are:

• sensors.c
  • contains startup for kx134_1211.c, a3g4250d.c, bmp581.c
• drivers.c
  • contains startup for all peripheral RCC, SPI for flash and LoRa, UART for GPS, and GPIO for buzzers and outputs
  • RCC, GPIO and relevant peripheral initialisation should be extracted to related device drivers

Motivation

This refactor not only benefits the overall readability and ease of maintenance of the system, but it also allows for greater portability as each device driver can have its initialisation parameters passed to it for startup.

This means that the parameters may be supplied as pre-processor definitions to allow for configurations to be easily adjusted (i.e. in the case of changes to hardware port connections).

Dependencies

• Refactor gps.c
• Refactor can.c
