mach-k3: add dynamic mmu fixups for SPL stage
On platforms with spl splash support i.e CONFIG_VIDEO=y, the top of DDR
is reserved for the framebuffer.
The size for the framebuffer is computed at runtime by video_reserve.
During the MMU configuration an entry corresponding to the framebuffer
should be dynamically created to properly map the required space for the
framebuffer.
Therefore this patch adds k3_spl_mem_map_init which adds the required
MMU entry by querying the gd after the framebuffer size has been
computed in spl_reserve_video_from_ram_top.
For non VIDEO=y platforms, the added k3_spl_mem_map_init function gets
optimized out of the final binary so overall, the spl size is not
impacted[1].
[1]: Tested on clang 19.1.7 and gcc 15.1.1
