drm/xe: Add vram frequency sysfs attributes
Add vram frequency sysfs attributes under the below hierarchy;
/device/tile#/memory/freq0
|-max_freq
|-min_freq

v3: Add documentation for new sysfs (Riana)
Drop prefix from XEHP_PCODE_FREQUENCY_CONFIG (Riana)
v4: Create sysfs under tile#/freq0 after removal of
physical_memsize attrbute
v5: Revert back to creating sysfs under tile#/memory/freq0
Remove definition of GT_FREQUENCY_MULTIPLIER (Rodrigo)
v6: Rename attributes to max/min_freq (Anshuman)
Fix review comments (Rodrigo)
v7: Make documentation more verbose
Move sysfs to separate file (Anshuman)
v8: Fix platform specific conditions and add kernel doc (Anshuman)
