This reverts commit 059323fb6a8f21637bb617919715c2427f24777c.
This commit 059323fb6a8f21637bb617919715c2427f24777c use JESD79-3E which
is not the newest spec. Should use JESD79-3F in which tRFC is 260ns for
4Gb chip.

We have CONFIG_MXC_OCOTP and CONFIG_CMD_FUSE in mx6_common.h,
discard duplicated macro definitions in board header files.
