radv: don't use hw resolves for r16g16 norm formats.

Browse source 
radeonsi has a workaround for this, but it uses a R16A16 format,
which vulkan doesn't have, we could probably come up with a work
around but for now just avoid hw resolves.

Fixes:
dEQP-VK.renderpass.suballocation.multisample.r16g16_*norm*
