drm/amd/display: Avoid overflow assignment in link_dp_cts
sampling_rate is an uint8_t but is assigned an unsigned int, and thus it
can overflow. As a result, sampling_rate is changed to uint32_t.
Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should
only be assigned to a value less or equal than 4.
This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.
