drm/amd/display: Update get_pixel_clk_frequency() for DCN4x DCCG DP DTO

[Why & How]
DCN4x ASICs have different DCCG logic for programming DP DTO. The current
get_pixel_clk_frequency_100hz() function does not account for this.

Rename the function to "get_dp_dto_frequency" to more accurately
reflect its intended behaviour. Create a new function that correctly
calculates the target pixel rate for DCN4.x DCCG design and use it.
