mtd: nand: pxa3xx: Use 'length override' in ONFI paramater page read

The ONFI command 'parameter page read' needs a non-standard length.
Therefore, we enable the 'length override' field in NDCB0 and set
a non-zero 'length count' in NDCB3.

Additionally, the 'spare enable' bit must be disabled for any command
that sets a non-zero 'length count' in NDCB3.
