mtd: denali: use CONFIG_SYS_NAND_SELF_INIT
Some variants of the Denali NAND controller need some registers
set up based on the device information that has been detected during
nand_scan_ident().
CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between
nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce
the difference between this driver and its Linux counterpart because
this driver was ported from Linux. Moreover, doc/README.nand recommends
to use CONFIG_SYS_NAND_SELF_INIT.
