Refactor common functions into files
Refactor common functions into files that can be reused by other
platforms. This is just a start, but make it so we can put different
platform init routines in other files and still access the functions
for gpio i2c and filesystem helpers.
Tested:
flash onto a gb200, log output was clean.
