[PATCH 13/13] mtd: spinand: winbond: Add continuous read support for W25N04LW

[Miquel Raynal]

LW chips follow the existing patterns, we can reuse the existing
set_cont_read() helper as well as the existing continuous read variants.

$ nandcontreadtest /dev/mtd0
testing 2 blocks from 0 to 1 (2 good), seed 22
success: verified 524288 bytes read in 405.770 ms (1261.80 KiB/s)

$ flash_speed /dev/mtd0 -C
1 page read speed is 1230 KiB/s
2 page read speed is 1242 KiB/s
3 page read speed is 1247 KiB/s
4 page read speed is 1261 KiB/s
5 page read speed is 1263 KiB/s
6 page read speed is 1263 KiB/s
7 page read speed is 1266 KiB/s
8 page read speed is 1261 KiB/s
9 page read speed is 1272 KiB/s
10 page read speed is 1269 KiB/s
11 page read speed is 1271 KiB/s
12 page read speed is 1269 KiB/s
13 page read speed is 1268 KiB/s
14 page read speed is 1272 KiB/s
15 page read speed is 1276 KiB/s
16 page read speed is 1273 KiB/s
32 page read speed is 1273 KiB/s
64 page read speed is 1261 KiB/s
