R110

--Linux upstream 4.14.243
--Slmk update
--Latest tag 'LA.UM.9.1.1.r1-00400-RENNELL.0' merged in for
qcacld, qcacmn, fw-api and (audio/data)-kernel
--Revert CAF's changes for UART GSI
--Fix up device freeze issue since Linux 4.14.240 (Thanks @freak07 's work)

Note: Some users report that after flash my kernel (R109), they can't completely boot their device, they freeze at boot animation, i don't know whether this version will still have this issue or not, but if you face it, try reboot more times can perfectly resolve it. : )
