MDSS.9.0 adds support for mdp vsync based HW timestamps
on top the existing support for panel vsync based timestamps.
This allows us to enable vsync timestamp calculations for all the
use cases including a few corner cases (e.g. programmable fetch)
which we couldn't support with the existing HW.
This change adds the new HW register support and modifies the
timestamp read logic to use mdp vsync on supporting targets.

Dedicated registers are introduced for DSC 4HS merge block
programming from MDSS.9.0. This change adds support in the
driver to identify the change using a DSC feature flag
and separates out 4HS merge block programming to use appropriate
registers based on the DSC HW feature.

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.

Currently, in dsi_display_get_modes, priv_info, rates,
front_porches and pixel_clks_khz memory is allocated for each
timing node and the same memory is copied for each supported fps.
The values of front porches calculated to maintain constant fps for
each bit clk rate gets overwritten with the values for last fps in
the dfps list. But the values of front porches should be different
in case where DFPS and dynamic clock are both supported either by
vfp approach or hfp approach. To fix this, allocate memory
separately for each fps.
