drivers/intel/dptf: Add OEM variables support
This adds OEM variables feature under DPTF as per BWG doc #541817. Using
this, platform vendors can expose an array of OEM-specific values as OEM
variables to be used in determining DPTF policy. These are obtained via
the ODVP method, and then simply exposed under sysfs. In addition, these
gets updated when a notification is received or when the DPTF policy is
changed by userspace.
