Calls init functions of dss_features during dss_probe, and the following
features are made omapxxxx independent:
- number of managers, overlays
- supported color modes for each overlay
- supported displays for each manager
- global aplha, and restriction of global alpha for video1 pipeline
- The register field ranges : FIRHINC, FIRVINC, FIFOHIGHTHRESHOLD
FIFOLOWTHRESHOLD and FIFOSIZE

Reorganize scaler FIR filter data as FIR value tables from raw
register values. This makes them easier to understand and simplifies
register programming code.
No functional changes.

Previously a work was started on FRAMEDONE interrupt, and this work
either sent a BTA synchronously or looped until TE_SIZE was zero, to
wait for the end of the transfer.
This patch changes a BTA to be sent asynchronously from FRAMEDONE
interrupt, and when a BTA interrupt is received, the transfer is
finished. This way we do the whole process asynchronously, and also
inside interrupt context.
This will give us much better latency to handle the end of the frame
than with the previous work based solution.

When DSS transitions from off mode to on VENC may generate a spurious
SYNC_LOST_DIGIT error. Just ack it when restoring the context. Also
restore IRQENABLE last to avoid triggering interrupts before the
context is fully restored.

Move enable/disable/suspend/resume from omap_dss_device to
omap_dss_driver.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.
