panfrost: Fix tiled NPOT textures with bpp<4

Browse source 
Panfrost's tiling routines (incorrectly) ignored the source stride,
masking this bug; lima's routines respect this stride, causing issues
when tiling NPOT textures whose stride is not a multiple of 64
(for instance, NPOT textures with bpp=1).
