onenand: Handle various ID fields separately

Browse source 
Handle the manufacturer, device and version IDs separately rather than
smooshing them all together into a single uint32_t. Note that the ID
registers are actually 16 bit, even though typically the top bits are 0
and the Read Identification Data command only returns the bottom 8 bits.
