mtd: denali: set some registers after nand_scan_ident()

Some but not all of implementations of the Denali NAND controller
have hardware circuits to detect the device parameters such as
page_size, erase_size, etc.  Even on those SoCs with such hardware
supported, the hardware is known to detect wrong parameters for some
nasty (almost buggy) NAND devices.  The device parameters detected
during nand_scan_ident() are more trustworthy.

This commit sets some hardware registers to mtd->pagesize,
mtd->oobsize, etc. in the code between nand_scan_ident() and
nand_scan_tail().
