ipq40xx: Remove kernel 4.14 support

This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

-Subject: [PATCH] mtd: nand: use usual return values for the ->erase() hook
-
-Avoid using specific defined values for checking returned status of the
-->erase() hook. Instead, use usual negative error values on failure,
-zero otherwise.
