Subject: drm/msm/a6xx: Add speedbin support for A619 GPU
Git-commit: fba6767c2dabcfaed0a8abf77fde0a8cb1b9fe10
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

There are various SKUs of A619, ranging from 565 MHz to 850 MHz, depending
on the bin. Add support for distinguishing them, so that proper frequency
ranges can be applied, depending on the HW.
