drm/amd/display: Don't build DCN1 when kcov is enabled

Browse Source 
DCN1 contains code that utilizes fp math. When
CONFIG_KCOV_INSTRUMENT_ALL and CONFIG_KCOV_ENABLE_COMPARISONS are
enabled, build errors are found. See this earlier patch for details:

https://lists.freedesktop.org/archives/dri-devel/2018-August/186131.html

As a short term solution, disable CONFIG_DRM_AMD_DC_DCN1_0 when
KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. In
addition, make it a fully derived config, taking into account
CONFIG_X86.
