ath79: 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 31/33] MIPS: ath79: drop !OF clock code
-
-With the target now being fully OF based, we can drop the legacy clock
-registration code. All clocks are now probed via devicetree.
