Hi all,

Changes since 20130724:

on i386:

# CONFIG_MFD_SYSCON is not set


when ahci_imx.c is built as a loadable module:

ERROR: "syscon_regmap_lookup_by_compatible" [drivers/ata/ahci_imx.ko] undefined!

or when it is builtin:

ahci_imx.c:(.text+0x182e54): undefined reference to `syscon_regmap_lookup_by_compatible'

We should have it depend on MFD_SYSCON.
