mtd: denali: use 8 bytes for READID command
The Denali NAND driver reads only 5 bytes of ID, but some Hynix and Samsung have size parameters in the 6th byte. As a result, the page and oob size for a Hynix H27UAG8T2B were calculated incorrectly and the driver failed to load. The solution is to read 8 bytes of ID, as expected by the NAND framework.
