drm/fourcc: Add 64 bpp half float formats
Add 64 bpp 16:16:16:16 half float pixel formats. Each 16 bit component is
formatted in IEEE-754 half-precision float (binary16) 1:5:10
MSb-sign:exponent:fraction form.
This patch attempts to address the feedback provided when 2 of these
formats were previosly proposed:
https://patchwork.kernel.org/patch/10072545/
v2:
- Fixed cpp (Ville)
- Added detail pixel formatting (Ville)
- Ordered formats in header (Ville)
v5:
- .depth should be 0 for new formats (Maarten)
