bcm63xx: remove support for kernel 4.19

Since stable kernel for this target is still 4.14, kernel 4.19
has never been used much (and actually was broken for some devices).

So, since we bump testing kernel to 5.4, there is no real need to
keep 4.19 and have an additional version to care about.

-Subject: [PATCH 01/11] MIPS: BCM63XX: add USB host clock enable delay
-
-Knowledge of the clock setup delay should remain at the clock level (so
-it can be clock specific and CPU specific). Add the 100 milliseconds
-required clock delay for the USB host clock when it gets enabled.
