Subject: drm/amd/display: Expose support for xBGR ordered fp16 formats.
Git-commit: 2a5195dca0b7058e65443416a20680be985d8753
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Expose support for DRM_FORMAT_ABGR16161616F and
DRM_FORMAT_XBGR16161616F to the DRM core, complementing
the already existing xRGB ordered fp16 formats.
These are especially useful for creating presentable
swapchains in Vulkan for VK_FORMAT_R16G16B16A16_SFLOAT.
