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

[Vitaliy Shevtsov]

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. On some systems
where long is 32 bits and one of these input 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. Also
this will align the function's definition with similar functions in other
dcn* drivers.

Found by Linux Verification Center (linuxtesting.org) with Svace.
