Update intel-gpu-freq.sh script to offer the possibility to adjust CPU
operating frequencies in addition to GPU.
Note this is currently limited to just setting the maximum scaling
frequency as percentage of the maximum frequency allowed by the
hardware.

Add script to manage Intel GPU frequencies.
It can be used for debugging performance problems or to lock a stable
frequency while executing benchmark tests.
Typical use cases:
- Get all available GPU frequency information
$ ./intel-gpu-freq.sh -g all
* Hardware capabilities
RP0: 1350 MHz
RPn: 100 MHz
RP1: 400 MHz
* Enforcements
max: 1350 MHz
min: 100 MHz
boost: 1350 MHz
* Actual
act: 100 MHz
cur: 400 MHz
- Lock frequency to 80% of the maximum allowed by hardware and enable
throttling detection
$ ./intel-gpu-freq.sh -s 80% -d
GPU throttling detected: act=1050 min=1350 cur=1350 RPn=100
GPU throttling detected: act=1100 min=1350 cur=1350 RPn=100
