drm/mipi-dbi: Prepare framebuffer copy operation in pipe-update helpers
Move the vmap/vunmap blocks from the inner fb_dirty helpers into the
MIPI DBI update helpers. The function calls can result in waiting and/or
processing overhead. Reduce the penalties by executing the functions once
in the outer-most function of the pipe update.
This change also prepares for MIPI DBI for shadow-plane helpers. With
shadow-plane helpers, transfer source buffers are mapped into kernel
address space automatically.
v2:
* keep each driver's existing buffer-mapping patter (Noralf)
* zero-initialize iosys_map arrays (Noralf)
