drm/amd/display: add support for per-state dummy-pstate latency

[why]
Dummy pstate latency actually varies between different
UCLK frequencies, when calculating watermark C, if DAL
always assumes worst case, then it can lead to dummy
pstate not supported scenarios.

[how]
Rather than statically calculating dummy pstate using
worst case, we store the entire table of UCLK to dummy
pstate relationships.  On a per mode basis, we calculate
the actual UCLK lower limit, and use the dynamic worst
case dummy pstate latency.  This prevents the situation
where we don't support full p-state (which will force
high DPM), but still use low DPM dummy pstate latency.

2. Use FPU flags only in the file that handles FPU operations;
3. Isolate all functions that require float point operation in static

4. Add a mid-layer function that does not use any float point operation,

5. Keep float point operation under DC_FP_{START/END} macro.

drm/amdgpu: Fix a buffer overflow handling the serial number

The comments say that the serial number is a 16-digit HEX string so the
buffer needs to be at least 17 characters to hold the NUL terminator.

The other issue is that "size" returned from sprintf() is the number of
characters before the NUL terminator so the memcpy() wasn't copying the
terminator.  The serial number needs to be NUL terminated so that it
doesn't lead to a read overflow in amdgpu_device_get_serial_number().
Also it's just cleaner and faster to sprintf() directly to adev->serial[]
instead of using a temporary buffer.
