drm: xlnx: zynqmp_dpsub: Minimize usage of global flag

Browse source

Avoid usage of global zynqmp_dpsub.dma_enabled flag in DPSUB layer
context. This flag signals whether the driver runs in DRM CRTC or DRM
bridge mode, assuming that all display layers share the same live or
non-live mode of operation. Using per-layer mode instead of global flag
will simplify future support of the hybrid scenario.

Remove redundant checks in DMA request/release contexts as
zynqmp_disp_layer.info is well-defined for all layer types, including the
correct number of DMA channels required for each particular layer.
