kernel: move Toshiba-TC58NVG0S3H patch to ipq40xx
Hannu Nyman wrote in openwrt's github issue #9962:
|Based on forum discussion, the commit 0bc794a

|Fritzbox devices, as the commit only defines a 4-byte flash

|See discussion from this onward

|OpenWrt 22.03.0-rc2 and rc3 are causing on a Fritzbox 7412

|Yup, that patch is missing the 5th ID byte entirely - both chips
|share the same first 4;

| TC58NVG0S3HTA00 = 0x98 0xf1 0x80 0x15 0x72 (digikey datasheet, page 35)
| TC58BVG0S3HTA00 = 0x98 0xf1 0x80 0x15 0xf2 (digikey datasheet, page 28)

|The commit has also been backported to openwrt-22.03 after rc1,

Andreas' TC58NVG0S3H seems not to follow Toshibas/Kioxa's own datasheet.
It only reports the first four bytes: "98 f1 80 15 00 00 00 00".
This patch changes the id_len in the entry to 8. This makes it so that
Andreas' NAND is still detected. At the same time, this prevents other
Toshiba NAND flash chips - that share the same four bytes - from being
misdetected.
Upstream (Miquel Raynal) decided to drop this patch for now. But he
advised to keep it in OpenWrt. As other devices could be affected.
