This change updates the ti-soc-thermal driver to use
standard GPIO DT bindings to read the GPIO number associated
to thermal shutdown IRQ, in case the device features it.

Previously, the code was using a specific DT bindings.
As now OMAP supports the standard way to model GPIOs,
there is no point in having a ti specific binding.

To reduce thermal maintenance load on Rui, SoC specific patches would be
applied by me now. Rui Zhang will pull in these changes from time to time (at
rc's). Additionally I would be sending him pull request for every merge
window and rc's (for fixes).

Branch names would be: next and fixes.

Fix build error in x86_pkg_temp_thermal.c.  It requires that
X86_MCE & X86_THERMAL_VECTOR be enabled, so depend on the latter symbol,
since it depends on X86_MCE (indirectly).

Also, X86_PKG_TEMP_THERMAL is already inside an "if THERMAL" block,
so remove that duplicated dependency.

This driver register CPU digital temperature sensor as a thermal
zone at package level.
Each package will show up as one zone with at max two trip points.
These trip points can be both read and updated. Once a non zero
value is set in the trip point, if the package package temperature
goes above or below this setting, a thermal notification is
generated.

In case emulated temperature is in use, using the trend
provided by driver layer can lead to bogus situation.
In this case, debugger user would set a temperature value,
but the trend would be from driver computation.

To avoid this situation, this patch changes the get_tz_trend()
to consider the emulated temperature whenever that is in use.

This patch adds the thermal data for TI DRA752 chips.
In this change it includes (autogen):
. Register offset definitions
. Bitfields and masks for all registers
. Conversion table

Also, the thermal limits, thresholds and extrapolation
rules are included. The extrapolation rule is simply
add +2C as margin.

All 5 sensors, MPU, GPU, CORE, DSPEVE and IVA, are defined
and exposed. Only MPU has cooling device.

This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).

For this reason this patch is changing the driver after
revisiting the code. These are the cases:
i. For cases in which IS_ERR_OR_NULL() is used for checking
return values of functions that returns either PTR_ERR()
or a valid pointer, it has been translated to IS_ERR() check only.
ii. For cases that a NULL check is still needed, it has been
translated to if (!ptr || IS_ERR(ptr)).

The variable 'descend' is initialized as -1 in function get_property(),
and will never get any chance to be updated by the following code.

	if (freq != CPUFREQ_ENTRY_INVALID && descend != -1)
		descend = !!(freq > table[i].frequency);

This makes function get_property() return the wrong frequency for given
cooling level if the frequency table is sorted in ascending.  Fix it
by correcting the 'descend' check in if-condition to 'descend == -1'.
