[why]
Conditionals in the DML basic math functions significantly impact mode
enumeration.
[how]
Remove conditionals for floor/ceil operations which are used frequently
in DML and add an assertion for invalid callers using zero granuality.
Fix existing callers that rely on 0 granularity.

Current implementation is slightly inaccurate and will often
result in truncation/floor operation decrementing an exact
integer output by 1.
Only rounded down output is ever expected, just extract the fp
exponent for this to increase performance and avoid any
truncation issues.

This change removes internal rounding in dml_log2 function.
Dml_log2 is expected to return a float output. In case an int is needed
dml will floor the output on it's own.

During the rework for removing the FPU issues, I found the following
warning:
[..] dml_common_defs.o: warning: objtool: dml_round()+0x9: FPU
instruction outside of kernel_fpu_{begin,end}()
This file has a single function that does not need to be in a specific
file. This commit drop dml_common_defs file, and move dml_round function
to dml_inline_defs.

This reduces the code size.
This is basically a redo of Dave's change with the same name
on top of the latest DML.

This reverts commit 3e8c3108dab197858e74dbb740c5312ae636ea9b.
Unfortunately these clash with our DML update from the HW guys.
Will attempt to reroll them after.
