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 08/13] i2c: qup: use the complete transfer length to choose
- DMA mode
-
-Currently each message length in complete transfer is being
-checked for determining DMA mode and if any of the message length
-is less than FIFO length then non DMA mode is being used which
-will increase overhead. DMA can be used for any length and it
-should be determined with complete transfer length. Now, this
-patch selects DMA mode if the total length is greater than FIFO
-length.
