  Now that socinfo SMEM item struct and defines have been moved to a header
so we can utilize that instead.

Now the SMEM value can be accesed directly, there is no need for defining
the ID for the SMEM request as well.

@Rafael, @Viresh, would you mind providing an Ack for me to take these 3
patches, together with patch 1, through the Qualcomm tree? I have staged
changes for 6.3, so we'll otherwise end up with conflicts on the move of
the struct.

Thanks,
Bjorn
