drm/xe/hwmon: Enable energy attributes for CRI

Browse Source 
Enable HWMON energy attributes for CRI, which are available through MMIO
registers.
Although these attributes can also be accessed via PMT, MMIO is preferred
as it avoids dependency on ocode firmware load in late binding scenario.

v2: Rephrase commit message. (Anshuman)
