Nick Hamilton 28f3e82f2d pco: Fix for atomic operations on an image buffer 
Within the driver buffers are treated as 2D as sampling them as 1D
will run into HW restrictions on max size.

The compiler does the same however for atomic image ops the address
is manually calculated and doing this via the 2D path leads to
incorrect offsets.

The fix is to treat buffers as 1D for atomic ops which calculates
the correct offsets for the operations.

Fix deqp:
dEQP-VK.image.atomic_operations.add.buffer.*
dEQP-VK.image.atomic_operations.and.buffer.*
dEQP-VK.image.atomic_operations.compare_exchange.buffer.*
dEQP-VK.image.atomic_operations.dec.buffer.*
dEQP-VK.image.atomic_operations.exchange.buffer.*
dEQP-VK.image.atomic_operations.inc.buffer.*
dEQP-VK.image.atomic_operations.max.buffer.*
dEQP-VK.image.atomic_operations.min.buffer.*
dEQP-VK.image.atomic_operations.or.buffer.*
dEQP-VK.image.atomic_operations.sub.buffer.*
dEQP-VK.image.atomic_operations.xor.buffer.*

Fixes: 6dc5e1e109 ("pco: fully support Vulkan 1.2 image atomics")
