MTD: kernel-doc fixes + additions

Fix some kernel-doc typos/spellos.
Use kernel-doc syntax in places where it was almost used.
Correct/add struct, struct field, and function param names where needed.

For most boards it will be sufficient to provide just the
basic functions and fill out some really board dependend
basic functions and fill out some really board dependent
members in the nand chip description structure.
