Subject[PATCH 1/2] cpufreq: scpi: add thermal dependency
Date
A built-in scpi cpufreq driver cannot link against a modular
thermal framework:

drivers/cpufreq/scpi-cpufreq.o: In function `scpi_cpufreq_ready':
scpi-cpufreq.c:(.text+0x4c): undefined reference to `of_cpufreq_cooling_register'
drivers/cpufreq/scpi-cpufreq.o: In function `scpi_cpufreq_exit':
scpi-cpufreq.c:(.text+0x9c): undefined reference to `cpufreq_cooling_unregister'

This adds a Kconfig dependency that makes sure this configuration
is not possible, while allowing all configurations that can work.
Note that disabling CPU_THERMAL means we don't care about the
THERMAL dependency.

This adds the CPUfreq driver support for ARM platforms using SCPI
protocol for CPU power management.
