[PATCH 10/11] mtd: cfi-flash: Coding style cleanup

[Sascha Hauer <s.hauer@pengutronix.de>]

- use consistent variable types (drop uchar, ushort and friends)
- remove whitespace between functions and opening brace
- Add some blank lines to rectify code
- drop 'rc' and 'retcode' and use 'ret' consistently
- Do not put variable assignment into if()
- drop unncessary braces
