drm/amd/display: fix type mismatch in CalculateDynamicMetadataParameters()

There is a type mismatch between what CalculateDynamicMetadataParameters()
takes and what is passed to it. Currently this function accepts several
args as signed long but it's called with unsigned integers and integer. On
some systems where long is 32 bits and one of these unsigned int params is
greater than INT_MAX it may cause passing input params as negative values.

Fix this by changing these argument types from long to unsigned int and to
int respectively. Also this will align the function's definition with
similar functions in other dcn* drivers.

The last use of optc3_fpu_set_vrr_m_const() was removed in 2022's
commit 64f991590ff4 ("drm/amd/display: Fix a compilation failure on PowerPC
caused by FPU code")
which removed the only caller (with a similar) name.

Remove it.
