drm/amdgpu: Fix CP_HYP_XCP_CTL register programming in CPX mode

Browse Source 
Currently, in CPX mode, the CP_HYP_XCP_CTL register is programmed
incorrectly with the number of XCCs in the partition. As a result,
HIQ doesn't work in CPX mode. Fix this by programming the correct
number of XCCs in a partition, which is 1, in CPX mode.
