[PATCH v2 11/23] mtd: spi-nor: winbond: W25QxxJV-Q/N/M: Add quad page program capability

[Miquel Raynal]

I do not have any W25Q256JV-Q/N/M nor any W25Q16JV-M chips in hand, but
all the chips with a density <= 256Mib are older revisions of the JV
chips which do not yet implement the 4BAIT extension table, as such,
they cannot advertise their quad page program capability. We can
reasonably expect that these chips follow the exact same rules, so add
the missing flag.

The QUAD_PP 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.
