[PATCH v2 08/23] mtd: spi-nor: winbond: W25Q32JV-M: Add quad page program capability

[Miquel Raynal]

This chip does not advertise it correctly but it supports 1-1-4 page
programs.

Before:

$ flash_speed /dev/mtd0 -d -c10
eraseblock write speed is 2612 KiB/s
page write speed is 2509 KiB/s
2 page write speed is 2560 KiB/s

After:

$ flash_speed /dev/mtd0 -c10 -d
eraseblock write speed is 3033 KiB/s
page write speed is 2895 KiB/s
2 page write speed is 2976 KiB/s

The CMP capability was historically not supported by non-SFDP chips, so
a Winbond wide late hook already makes sure the bit remains disabled for
them, for backward compatiblity reasons.
