Fix Sharp LHF00L04

Browse Source 
- Add eraseblock definitions
- Use correct eraseblock sizes (the datasheet is a bit ambiguous)
- Use correct probe function
- Fill in probe timing

There is a lot more stuff left to clean up, but at least probe and erase
should work now.

Corresponding to flashrom svn r837.
