We retrieve the byte and pixel source clocks (RCG clocks) in the dsi
driver via DT. These are needed so that we can re-parent these source
clocks if we want to drive it using a different DSI PLL.
We shouldn't get these via DT because they aren't clocks that directly
serve as inputs to the dsi host.
Fortunately, there is a static parent-child link between the
byte_clk_src/pixel_clk_src and byte_clk/pixel_clk clocks. So, we can
retrieve the source clocks via clk_get_parent.
Do this instead of retrieving via DT.

Create DSI encoders during modeset_init. The 2 encoders should ideally be
one command mode and one video mode DSI encoder respectively, but we don't
support command mode yet. We just create 2 of the same because the dsi
driver expects it, we end up using only the first one.

The mdp_kms round_pixclk op creates problems when we have more
interfaces in use. It calls the DTV encoder's helper by default.
Check on encoder type and call the corresponding encoder's
func meant for rounding pixel clock. DSI and LVDS don't require
rounding, so just return rate in their case.

Currently, the driver defers if it doesn't find a drm_panel. This forces
us to have a drm_panel, if not, the driver isn't usable.
Make the lcdc encoder initialization independent of the availability of
the drm panel. We only check if there is a panel node specified in DT. If
it isn't, then we don't initialize the encoder at all. The panel node is
passed to the lcdc encoder and lvds connector drivers.
The connector driver takes the responsibility to retrieve the drm_panel
from the panel node, and update the status on whether the panel is
connected or not. This makes the panel usable even if the drm_panel
driver is inserted as a module later on.

MDP5 has line count and frame count registers for each interface. Enable
these counters and use them to implement the get_vblank_timestamp drm

The line counter starts with the value 1 at the beginning of the VSYNC
pulse and ends with value VTOTAL at the end of VFP. This value is used
to determine whether we're in blanking period or not, and an adjusted
value of this counter is used to get vpos as expected by
get_scanout_position. Since there is no way to calculate hpos, we always
set it to 0.
