The offsets are the same as for MT6797. Could we rename the define to something
generic and move it up and put it just under SPM_PWR_STATUS_2ND? Probably as a
separate patch.

Loop more related owners in this mail loop.

After check it with our clock driver owners, there are different
generations of clock IPs. Because different smart phone chips require
different cost-function oriented design, even they use the same
generation of clock IPs, might not have the same offsets. Take MT6765
and MT6797 for example, the listed offsets are just coincidence.

Our clock driver owners will work on this to summarize the common offset
parts for each generations, but at this moment, we suggest just separate
the files for mt6797 and mt6765. Commonly used header should be come
with the next chip which clock IP just the same generation of mt6797 or
mt6765.

Thanks
