drm/amd/display: Refine i2c frequency calculating sequence
[Why] In HG mode, vbios didn't call DispController_Init to program NV1x XTAL_REF_DIV value when ASIC_INIT, but driver read XTAL_REF_DIV to calculate i2c reference frequency. it cause i2c frequency change from 100kHz to 200kHz. [How] remove get_speed function and calculate reference frequency at set_speed functiton.
