SBL will configure IPQ807x cores to boot at 800MHz as a safe default
frequency that is provided by GPLL0, but GPLL0 is not currently configured
as a possible parent in the APSS clock driver not being passed to it via
DTS which will then cause the kernel to not properly identify the current
CPU frequency during booting and will think that CPU is currently at XO
frequency of 19.2MHz instead of 800MHz cores are actually at and print:
cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 19200 KHz, changing to: 1017600 KHz
So, lets import patches pending upstream to prevent GPLL scaling and feed
the GPLL0 clock to APSS clock driver so we get:
cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 800000 KHz, changing to: 1017600 KHz
This is mostly cosmetic fix, but with all of the possible SBL and FW
versions there could be edge cases resolved by this and not scaling GPLL-s
anymore.
