When there is CPU processing delay between first INTR clear and
second INTR clear there is a chance that the second register
write might clear the next frames interrupts which will avoid
triggering the irq callbacks causing software hung. This
patch avoids such a scenario by removing such double clearing
of INTR registers.

For second dedicated CWB pingpong blocks, the overflow irq needs

There is little sense in reading interrupt statuses and right after that
going after the array of statuses to dispatch them. Merge both loops
into single function doing read and dispatch.

From Kalama, the HW scheduler abstracts the low level
PP_DONE/WB_DONE interrupts and generates a common
CTL_DONE interrupt per hw ctl. This saves the software
the irq latency delays to process the frame complete
operations when multiple encoders are involved.
If supported, this change enables and waits for the
CTL_DONE interrupt instead of PP_DONE and WB_DONE.
This change adds support to wait for CTL_DONE irq in
only command mode panels as we don't drive two WB blocks
with single CTL.

From MDSS 9.0, writeback supports a programmable lineptr support, which
generates an interrupt when the configured writeback output height is
reached. Add software support to configure the prog_line and to process
the interrupt.

Refactor the SDE interrupts module to use the offsets in the catalog.
This avoids hard-coding offsets for interrupts within a block's
address space so when that block's base address is relocated the
interrupts for that block are shifted as well.
