mtd: nand: Add a few more timings to nand_sdr_timings

Browse Source 
Add the tR_max, tBERS_max, tPROG_max and tCCS_min timings to the
nand_sdr_timings struct.
Assign default/safe values for the statically defined timings, and
extract them from the ONFI parameter table if the NAND is ONFI
compliant.
