Smatch reports:
1. mtk_thermal_probe() warn: 'apmixed_base' from of_iomap() not released.
2. mtk_thermal_probe() warn: 'auxadc_base' from of_iomap() not released.
The original code forgets to release iomap resource when handling errors,
fix it through unified error handling code at the end of mtk_thermal_probe.
Fixes: 89945047b166 ("thermal: mediatek: Add tsensor support for V2 thermal system")

I think the this should be released on the success path but I was too
scared of breaking things. Let me know and I will resend if people want
me to do that.

Better to use the devm_of_iomap() variant
And also take the opportunity to use devm_clk_get_enabled(), remove
clk_prepare_enable() and the rollbacking in the err_disable_clk_per*:
label sections.

Smatch reports:
1. mtk_thermal_probe() warn: 'apmixed_base' from of_iomap() not released.
2. mtk_thermal_probe() warn: 'auxadc_base' from of_iomap() not released.
The original code forgets to release iomap resource when handling errors,
fix it by switch to devm_of_iomap.

Notice the devm_clk_get_enabled do the clk_get and clk_prepare_enable
at the same time.
I'm not sure if this has any side effects in initialization.

If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Smatch reports:
1. mtk_thermal_probe() warn: 'apmixed_base' from of_iomap() not released.
2. mtk_thermal_probe() warn: 'auxadc_base' from of_iomap() not released.
The original code forgets to release iomap resource when handling errors,
fix it by switch to devm_of_iomap.
