drm/i915/adlp/fb: Fix remapping of linear CCS AUX surfaces

Browse source

During remapping CCS FBs the CCS AUX surface mapped size and offset->x,y
coordinate calculations assumed a tiled layout. This works as long as
the CCS surface height is aligned to 64 lines (ensuring a 4k bytes CCS
surface tile layout).  However this alignment is not required by the HW
(and the driver doesn't enforces it either).

Add the remapping logic required to remap the pages of CCS surfaces
without the above alignment, assuming the natural linear layout of the
CCS surface (vs. tiled main surface layout).
