anv: drop anv_ahb_format_for_vk_format

The vk_image::ahb_format is for drivers that support more than the
common explicit AHB formats. It is used on AHB image memory export
allocation path, and more specifically vk_device_memory_create will
use that AHB format to allocate the AHB out from gralloc. To be noted,
export allocation path only deals with explicit format but not external
format. So even with the obsolete HAL_PIXEL_FORMAT_NV12_Y_TILED_INTEL
private format, we don't need such either as multi-planar formats are
supposed to be reported as external format.
