freedreno: add has_separate_chroma_filter to fd_dev_info

The blob driver does not support
VK_FORMAT_FEATURE_SAMPLED_IMAGE_YCBCR_CONVERSION_SEPARATE_RECONSTRUCTION_FILTER_BIT
before a6xx_gen3.  It still sets CHROMA_LINEAR bit according to
chromaFilter, but the bit has no effect before a6xx_gen3 (confirmed on
a618 with blob version 512.490.0).
