For ES2.0 devices, it is not guaranteed that current DTEMP
or DTEMP0 from the history buffer are going to contain
correct values, due to desynchronization between BG clk
and OCP clk.
For this reason, this patch changes the driver to first:
a. consider a feature flag, FREEZE_BIT, in order to check
it is possible to freeze the history buffer or not.
b. whenever reading the temperature, it will fetch from
DTEMP1 instead of DTEMP or DTEMP0.
This WA is applicable only for OMAP5430 ES2.0.

This function is ugly because it hits against the 80 character
limit. This patch does several things to clean it up.
1) Introduces "result" instead of inf->info.chinforesult.result[n].
2) Reverses the ".scanchannels & (1 << i)" so everthing can be
pulled in one indent level.
3) Use "chan" instead of "channel".
4) Tweaks the line breaks to the call to pr_debug().
