[PATCH 0/7] memory: atmel-ebi: Add PM ops

This patchset adds a ->resume() hook to the EBI driver, but a few more
changes were required in order to easily implement this PM hook.
Patches 1 to 5 are just cleanup patches to simplify the EBI driver.
Patch 6 is fixing a bug in the EBI driver. Note that this bug has no
consequences until we start implementing the ->resume() hook.
And finally, patch 7 is implementing ->resume() so that the SMC config
is correctly restored when resuming the system.
This patchset depends on  which is removing the unused pata_at91
driver, which in turn prevents us from patching it before dropping
the old SMC macro definitions in patch 4.
Changes since v1:
- move helper functions in a C file
- check if tdf is at least ATMEL_SMC_MODE_TDF_MIN
