mvebu: 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: clk: mvebu: armada-37xx-periph: prepare cpu clk to be
- used with DVFS
-
-When DVFS will be enabled then the cpu clk will use a different set of
-register at run time. That means that we won't be able to use the common
-callback and need to use our own ones.
-
-This patch prepares this change by switching on our own set of callbacks
-without modifying the behavior of the clocks.
