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.

V2: Increase size of id_bytes array to 8.
