Several manufacturers and chips have been added since 4.19, several of which are used in devices already supported by OpenWrt (typically with no or "legacy" access to their NAND memory). This commit catches up the supported-chip definitions through Linux 5.2-rc6 and linux/next. The driver is only compiled for platforms with CONFIG_MTD_SPI_NAND=y. This presently includes ipq40xx and pistachio, with the addition of ath79-nand in these commits (and not ath79-generic or ath79-tiny).

ipq40xx: Add patches for 4.19 This adds the necessary patches for 4.19 kernel. Upstreamed patches were dropped, backported upstreamed patches from 4.20. Drop Winbond ID patch since that NAND IC was upstreamed to use SPI-NAND framework and support for it was backported from 4.20. Rework ESSEDMA patches to compile under 4.19 due to timer changes, Clément Péron did the hard work and his changes were taken from the initial 4.19 PR. MR33 changes had to be manually refreshed to apply. Refresh other patches to apply. Signed-off-by: Robert Marko <robimarko@gmail.com> Remove

W25N01GV is a single die version of the already supported
W25M02GV with half the capacity. Everything else is the
same so introduce support for W25N01GV.
