drm/amd: Drop all hand-built MIN and MAX macros in the amdgpu base driver

Several files declare MIN() or MAX() macros that ignore the types of the
values being compared. Drop these macros and switch to min() min_t(),
and max() from `linux/minmax.h`.

drm/amd/pm: fulfill the missing enablement for vega12/vega20 L2H and H2L interrupts

The feature mask bit was not correctly cleared. Without that, the L2H
and H2L interrupts cannot be enabled.

drm/amd/pm: drop the unnecessary intermediate percent-based transition

Currently, the readout of fan speed pwm is transited into percent-based
and then pwm-based. However, the transition into percent-based is totally
unnecessary and make the final output less accurate.

drm/amd/pm: correct the fan speed PWM retrieving

The relationship "PWM = RPM / smu->fan_max_rpm" between fan speed
PWM and RPM is not true for SMU11 ASICs. So, we need a new way to
retrieving the fan speed PWM.

drm/amd/pm: optimize the power related source code layout

The target is to provide a clear entry point(for power routines).
Also this can help to maintain a clear view about the frameworks
used on different ASICs. Hopefully all these can make power part
more friendly to play with.
