drm/tidss: dispc: Switch to drm_fb_dma_get_gem_addr() for framebuffer addresses

Browse source

dispc_plane_state_dma_addr() and dispc_plane_state_p_uv_addr() are
basically the same as drm_fb_dma_get_gem_addr(), without the support for
formats with block parameters. Since the driver doesn't support any of
those formats, the result is the same.

Switch to drm_fb_dma_get_gem_addr() for getting the framebuffer addresses.
Drop the const modifier on "struct drm_plane_state *state" for
dispc_plane_setup() so that the state can be passed to
drm_fb_dma_get_gem_addr().

Using the helper also future proofs the driver in case block parameters
are added for more formats, especially the common sub-sampled YUV
formats.
