Revert "mtd: onenand: add ecclayout and subpage_sft for non-flex 4KiB page onenand"
This reverts commit 99b17c08bca2810f5910b3027f1b9d82edf7a576. This change broke support for the onenand chip used in Nexus-S which is also reported as non-flex 4KiB pagesize. Change-Id: I1a9a30fa42491400a664fd42f574a099a0c29978 Signed-off-by: Arve Hjønnevåg <arve@android.com>
