mtd: nand: denali: clean up macros with <linux/bitfield.h>
All the register offsets and bitfield masks are defined in denali.h,
but the driver code ended up with additional crappy macros such as
MAKE_ECC_CORRECTION(), ECC_SECTOR(), etc.
The reason is apparent - accessing a register field requires mask and
shift pair. The denali.h only provides mask. However, defining both
is tedious.
<linux/bitfield.h> provides a convenient way to get register fields
only with a single shifted mask. Now use it.
While I am here, I shortened some macros.
