[computer_hardware][laptops] Enable AMD P-State driver for better battery life

[LukeShortCloud]

This is supported on Linux >= 6.3 and AMD Zen >= 2 processors. Set these boot arguments:

• amd_pstate=active (required)
• initcall_blacklist=acpi_cpufreq_init (optional, force the old power management driver to not load)

CPPC also needs to be enabled in the BIOS. Verify if it has been enabled:

$ lscpu | grep cppc
