Kernel for 4.19 rom
Changes:
- Dropped most xiaomi and power changes, but made it work with xiaomi thermal hal

DDR BUS was fine on sdm845 4.19 since the beginning, it was FKM doing wrong calculation, due to wrong path of sys. In FKM path is set to cpubw on 4.9 and to ddr-bw on 4.19(which is correct for non llcc devices, but wrong for us), that's why we were getting weird freqs on DDR BUS, that also happens on kona

Changes:
- Fixes for Awaken

Experimental kernel for 4.19 rom

What's different from other 4.19:
- CPUfreq_hw and devfreq_fw drivers instead of cpu osm + gov
- Simplified EAS instead of Legacy EAS

Probably single core perf is better, but multicore worser

If someone has issues with fastboot on Xiaomi devices connected by USB 3.0 there is bypass:

I'm leaving 4.19 Poco F1 Project due to ICPC and exams. Would continue working on 4.19 in ~ February

About 4.19 issues: camera focus is static(might need new S/R 4.9 camera stack to fix, also CameraIR works strange), need to adapt dts(qpnp pwm -> qti lpg) lm3644 changes, other stuff feels fine
