[PATCH] docs: mtd: Avoid htmldocs warnings

[Miquel Raynal]

Moving files around produced the following warnings:

       Error: Cannot open file drivers/mtd/nand/raw/nand_ecc.c
       Error: Cannot open file drivers/mtd/nand/raw/nand_ecc.c

Fix one by just dropping the reference because it is not relevant, the
other by using a better noun instead of a file name.

 Introduction
 ============
 
-Having looked at the linux mtd/nand driver and more specific at nand_ecc.c
+Having looked at the linux mtd/nand Hamming software ECC engine driver
 I felt there was room for optimisation. I bashed the code for a few hours
 performing tricks like table lookup removing superfluous code etc.
 After that the speed was increased by 35-40%.
