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 enables the interface hw block to accept
64-bit compressed pixels. This configuration is enabled based

the compressed pixels flow through the interface block,
whereas in the previous version of DPU hw this configuration
is only required for topology using 4 way dsc merge.

algorithms as they can support higher compression ratios.
