Rename dispc's manager related functions as follows:
- Remove prepending underscores, which were originally used to inform
that the clocks needs to be enabled. This meaning is no longer valid.
- Prepend the functions with dispc_mgr_*
- Remove "channel" from the name, e.g. dispc_enable_channel ->
dispc_mgr_enable
The idea is to group manager related functions so that it can be deduced
from the function name that it writes to manager spesific registers.
All dispc_mgr_* functions have enum omap_channel as the first parameter.

Remove support for non-DISPC overlays and overlay managers.
The support to possibly have non-DISPC overlays and managers was made to
make it possible to use CPU and/or sDMA to update RFBI or DSI command
mode displays. It is ok to remove the support, because:
- No one has used the feature.
- Display update without DISPC is very slow, so it is debatable if the
update would even be usable.
- Removal cleans up code.
- If such a feature is needed later, it is better implemented outside
omapdss driver.

Currently when changing the manager of an overlay, set_manager() directly
calls dispc to set the overlay's destination.
Change this to be more in line with other overlay configurations, and
this will also remove the need to have dispc clocks enabled when calling
set_manager().
A new field is added to overlay struct, "manager_changed". This is
similar to "display_changed" field in manager struct, and is used to
inform apply that the manager has changed and thus write to the
registers is needed.

Allow TX buffers to be allocated only in the upper 75% of the pool
to avoid a completely filled buffer preventing the driver from
processing responses. This also improves performance, as RX
allocations do not require checking buffers allocated for TX
unless there are more than 16 incoming messages -- which is
highly unlikely.
An earlier version used the lower 75% for TX messages, but
that was considered to be not that effective due to the
overlaps of RX and TX buffers mentioned above.
