ACPI: cpufreq: Switch to QoS requests instead of cpufreq notifier

Browse source 
The cpufreq core now takes the min/max frequency constraints via QoS
requests and the CPUFREQ_ADJUST notifier shall get removed later on.

Switch over to using the QoS request for maximum frequency constraint
for acpi driver.
