Cleanup of flash code

Browse Source 
Fix several bugs found in the write-flash code during installer coding.
Move all flash functions into CODE0. This is required to share these
functions with the installer image (currently they are duplicated so
they are not within the CODE1 segment).
De-magics all Flash command codes based on the Winbond W25Q32JV
datasheet.
