[PATCH 1/9] thermal: intel: hfi: Relocate bit definitions of HFI registers

[Ricardo Neri <ricardo.neri-calderon@linux.intel.com>]

From: Zhao Liu <zhao1.liu@intel.com>

KVM needs the definition of several HFI registers for the virtualization
of HFI. Move the necessary definitions to msr-index.h

While here, use BIT_ULL() and GENMASK_ULL() since the relevant registers
have 64 bits. Also, remove the "_BIT" suffix for consistency in naming.

No functional changes.
