[ Upstream commit 53d22794711ad630f40d59dd726bd260d77d585f ]

Let's select RATIONAL with dp driver. avoid like:

[...]
x86_64-linux-gnu-ld: drivers/gpu/drm/msm/dp/dp_catalog.o: in function `dp_catalog_ctrl_config_msa':
dp_catalog.c:(.text+0x57e): undefined reference to `rational_best_approximation'
