This patch refactors the BMP rendering logic, moving it from
drivers/intel/fsp2_0 to src/lib. This centralizes the code
responsible for rendering BMP images to the framebuffer.
Key changes:
- Move BMP rendering functions (e.g., calculate_logo_coordinates,
copy_logo_to_framebuffer) and their dependencies to
src/lib/render_bmp.c and src/lib/render_bmp.h.
- Decouple BMP definitions from UEFI headers by introducing new
coreboot-specific structures for BMP images and BLT pixels.
- Consolidate bootsplash-related declarations into bootsplash.h,
including new `fw_splash_vertical_alignment`,
`fw_splash_horizontal_alignment`, and `struct logo_config`.
- Update `soc_load_logo_by_coreboot` to use the new common
`load_and_render_logo_to_framebuffer` function and `struct
logo_config` for rendering.
- Relocate `release_logo` to `src/lib/render_bmp.c` for better
module structure.
- Update `src/lib/Makefile.mk` to include the new render_bmp.c.
This refactoring improves code organization and reusability, making
BMP rendering accessible without tight coupling to Intel-specific
driver code.
