cpufreq: imx6q: Don't disable 792 Mhz OPP unnecessarily

cpufreq: imx6q: Don't disable 792 Mhz OPP unnecessarily
[ Upstream commit 2e4e0984c7d696cc74cf2fd7e7f62997f0e9ebe6 ]
For a 900MHz i.MX6ULL CPU the 792MHz OPP is disabled. There is no convincing reason to disable this OPP. If a CPU can run at 900MHz, it should also be able to cope with 792MHz. Looking at the voltage level of 792MHz in [1] (page 24, table 10. "Operating Ranges") the current defined OPP is above the minimum. So the voltage level shouldn't be a problem. However in [2] (page 24, table 10. "Operating Ranges"), it is not mentioned that 792MHz OPP isn't allowed. Change it to only disable 792MHz OPP for i.MX6ULL types below 792 MHz.

cpufreq: imx6q: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void.
Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

cpufreq: imx6q: don't warn for disabling a non-existing frequency
It is confusing if a warning is given for disabling a non-existent frequency of the operating performance points (OPP). In this case the function dev_pm_opp_disable() returns -ENODEV. Check the return value and avoid the output of a warning in this case. Avoid code duplication by using a separate function.

cpufreq: Use of_property_present() for testing DT property presence
It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

cpufreq: imx6q: Fixes unwanted cpu overclocking on i.MX6ULL
imx6ul_opp_check_speed_grading is called for both i.MX6UL and i.MX6ULL. Since the i.MX6ULL was introduced to a separate ocotp compatible node later, it is possible that the i.MX6ULL has also dtbs with "fsl,imx6ull-ocotp". On a system without nvmem-cell speed grade a missing check on this node causes a driver fail without considering the cpu speed grade.
This patch prevents unwanted cpu overclocking on i.MX6ULL with compatible node "fsl,imx6ull-ocotp" in old dtbs without nvmem-cell speed grade.

cpufreq: imx6q/thermal: imx: register cooling device depending on OF
The cooling device should be part of the i.MX cpufreq driver, but it cannot be removed for the sake of DT stability. So turn the cooling device registration into a separate function and perform the registration only if the CPU OF node does not have the #cooling-cells property.
Use of_cpufreq_power_cooling_register in imx_thermal code to link the cooling device to the device tree node provided.
This makes it possible to bind the cpufreq cooling device to a custom thermal zone via a cooling-maps entry like:
cooling-maps { map0 { trip = <&board_alert>; cooling-device = <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>; }; };
Assuming a cpu node exists with label "cpu0" and #cooling-cells property.

treewide: devm_kzalloc() -> devm_kcalloc()

with:
treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with: devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:

This is a preparatory commit to make policy->suspend_freq independent of validation of the cpufreq table, as a later commit would update cpufreq_generic_init() to not validate the cpufreq table any longer.
The driver already assumes the order in which the frequency table is sorted and we can get the max frequency easily.
