mtd: rawnand: denali_dt: insert udelay() after reset deassert
When the reset signal is de-asserted, the HW-controlled bootstrap starts running unless it is disabled in the SoC integration. It issues some commands to detect a NAND chip, and sets up registers automatically. Until this process finishes, software should avoid any register access. Without this delay function, some of UniPhier boards hangs up while executing nand_scan_ident(). (denali_read_byte() is blocked) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
