new upstream version 4.19.63

[Harald Dunkel <harald.dunkel@aixigo.com>]

Hi folks,

since 4.19.37 there have been quite a number of new versions in
upstream's linux-4.19.y branch. I have to support recent hardware
for my Debian 9 systems, so I wonder what are your plans for buster
and stretch-backports?
