With commit c814a4c7c4, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.
As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new
attribute mapping does not reflect the actual usage of the threshold registers.
Also, register contents are changed during runtime by an entity other than the
hwmon driver, meaning the values cached by the driver do not reflect actual
register contents.
Revert most of c814a4c7c4 to address the problem.
Support for T0 and T1 will be added back in with a separate commit, using new
attribute names.

Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:
1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
accesses to some banked fan / pwm registers. On the f71889fg no registers
which we use are banked. On the f71889ed however some more fan registers
have been banked including one which we use, by making the FAN_PROG_SEL bit
0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
This is correct for the f71889ed and on the f71889fg 0 is a reserved
value, so we should never see it and if we do, disabling the pwm related
sysfs attr is a sane thing to do.

Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.
The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.
Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.
