v3dv/device: fix minTexelBufferOffsetAlingment 

As we understand that texture accesses should be aligned to the UIF
block size.

Fixes several of the CTS tests under this pattern:
  dEQP-VK.binding_model.shader_access.primary_cmd_buf.uniform_texel_buffer.*.offset_nonzero
  dEQP-VK.binding_model.shader_access.primary_cmd_buf.storage_texel_buffer.*.offset_nonzero

Note: for those tests, using a lower value (64) was enough to get them
working, but again, we understand that the real alignment is the UIF
block size.
