This RFC series aims to extend cpu based scaling support to L3/DDR on
SDM845 and SC7180 SoCs.

Patches [1-3] - Blacklist SDM845 and SC7180 in cpufreq-dt-platdev
Patches [5-7] - Hack in a way to add/remove multiple opp tables to
                a single device. I am yet to fix the debugfs to
		support multiple opp_tables per device but wanted to
		send what was working upstream to get an idea if multiple
		opp tables per device is a feature that will be useful
		upstream.
Patches [9-10] - Add the cpu/cpu-ddr/cpu-l3 opp tables for SDM845
                 and SC7180 SoCs.

v3:
 * Migrated to using Saravana's opp-kBps bindings [1]
 * Fixed some misc comments from Rajendra
 * Added support for SC7180

v2:
 * Incorporated Viresh's comments from:
 https://lore.kernel.org/lkml/20190410102429.r6j6brm5kspmqxc3@vireshk-i7/
 https://lore.kernel.org/lkml/20190410112516.gnh77jcwawvld6et@vireshk-i7/
 * Dropped cpufreq-map passive governor

Git-branch: https://github.com/QuinAsura/linux/tree/lnext-012420

Some alternate ways of hosting the opp-tables:

https://github.com/QuinAsura/linux/commit/3d23d1eefd16ae6d9e3ef91e93e78749d8844e98
Viresh didn't really like ^^ bindings and they dont really scale well. Just
including them here for completeness.

Depends on the following series:
[1] https://patchwork.kernel.org/cover/11277199/
[2] https://patchwork.kernel.org/cover/11055499/ 
[3] https://patchwork.kernel.org/cover/11326381/
