For constant fps feature, porch is calculated based on supported
clk rates. Currently, data type of local variables used for porch
calculation is u32 which leads to incorrect porch calculation for
higher clk rates. So, update the data type to u64.

For video mode panels, async wait feature for DCS command
transmission may not always be reliable as additional programming
would be needed to ensure that the DCS commands are correctly scheduled.
Until this feature is properly implemented and validated, disable this
for video mode panels to avoid potential DSI command transfer
failures.

The clock framework nulls the clock hardware init data, after a variant
of clk_register is called on the clk_hw pointer. This results in a null
pointer dereference when we try to call set rate in the PLL prepare
function. The call can be a direct call to the function rather than
trying to access through the init_data pointer of the clk_hw.

This change enforces dp, dsi and the sde drivers to use the
drm framework defined dsc_config data structure. As a part of this,
it introduces the sde_dsc_helper API to configure the dsc params
and creating a PPS command. Earlier each driver implemented it's
private versions leading to duplication of code. Additionaly the
helper api supports DSC spec 1.2 422 and 420 mode.
