google-crosshatch: upgrade mainline kernel to 5.3-rc5 (!577)

This rebases the Pixel 3 XL patches on top of Linux 5.3-rc5.

Also enabled more kernel modules related to modem, and applied
Bjorn Andersson's patch for resetting the UFS memory.

See
https://gitlab.com/postmarketOS/pmaports/issues/153
for more information.
