[PATCH 11/13] mtd: spinand: winbond: Add continuous read support for W25N04LV

[Miquel Raynal]

LV chips have DDR support, otherwise they support the same variants as
the other chips.

$ nandcontreadtest /dev/mtd0
testing 2 blocks from 0 to 1 (2 good), seed 29
success: verified 524288 bytes read in 291.735 ms (1755.02 KiB/s)

$ flash_speed /dev/mtd0 -C
1 page read speed is 1673 KiB/s
2 page read speed is 1718 KiB/s
3 page read speed is 1737 KiB/s
4 page read speed is 1741 KiB/s
5 page read speed is 1764 KiB/s
6 page read speed is 1764 KiB/s
7 page read speed is 1762 KiB/s
8 page read speed is 1753 KiB/s
9 page read speed is 1774 KiB/s
10 page read speed is 1764 KiB/s
11 page read speed is 1774 KiB/s
12 page read speed is 1777 KiB/s
13 page read speed is 1777 KiB/s
14 page read speed is 1763 KiB/s
15 page read speed is 1777 KiB/s
16 page read speed is 1790 KiB/s
32 page read speed is 1777 KiB/s
64 page read speed is 1777 KiB/s
