There is no need to use set_timer(). Replace with appropriate use of
get_timer()

Sorry Wolfgang, but this patch has been through a few versions before it
got integrated into the larger Timer API hence the v1->v2->v1 debacle.
checkpatch complains about long lines and brace usage in the board specific
flash.c files - They are deprecated and not worth fixing for style
Changes since v1 ((WIP) [Timer]API Rewrite):
- Rebased to 68d4230c3ccce96a72c5b99e48399bf1796fe3c6
Changes since V1:
- Fix typo in commit message
- Add reset_timer() to Nios2 get_timer(0)
Changes since V2
- No longer remove reset_timer()
