[PATCH V2] In the Denali NAND controller driver, use 8 bytes for READID command.

[Graham Moore]

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.
