disp: msm: sde: add support for split VBIF clock access

From Kalama onwards, the VBIF CLK_CTRL register has been moved from TOP block
to individual hardware block memory range.

This change is adding a backward compatible solution to support
per block VBIF CLK_CTRL access by allowing each HW block to register
set of callback ops. Additionally, it adds DMA and IPCC/MSI VBIF CLK_CTRL
block type.
