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 04/11] MIPS: BCM63XX: add OHCI/EHCI configuration bits to
- common USB code
-
-This patch updates the common USB code touching the USB private
-registers with the specific bits to properly enable OHCI and EHCI
-controllers on BCM63xx SoCs. As a result we now need to protect access
-to Read Modify Write sequences using a spinlock because we cannot
-guarantee that any of the exposed helper will not be called
-concurrently.
