Documentation: change linux-4.x references to 5.x 

As linux-5.0.x is coming up soon, the documentation should match,
in particular the README.rst file, so change all 4.x references
accordingly. There was a mix of lowercase and uppercase X here,
which I changed to using lowercase consistently.

Unlike patches for the 5.x kernels, patches for the 5.x.y kernels

patch -R) **before** applying the 4.0.3 patch. You can read more on this in
