mtd: spinand: gigadevice: Add continuous read support
GD5F1GM9 supports a high-speed Continuous Read (CR) mode which allows
the entire memory array to be read out by a single read command
without re-issuing the 13h “Page Read to Cache” command for every page.
Datasheet summary
Feature register B0[3] (NR bit)
1 = Normal Read (default)
0 = Continuous Read (CR)
ECC status register 7Ch
Normal read: bits [3:0] → ECC status of last page
Continuous read: bits [7:4] → accumulated max bit-flips over the
whole sequential read operation.
