Southern Islands support

Hello,

Thanks for the work you have done here, GPA is a really nice library. I see that you have added Volcanic Islands support in a recent release, and I was wondering if Southern Islands support for Vulkan is somewhere near in the roadmap.

I certainly know it's a kind of old architecture, but some GPUs using it (like E8860) are being actively used in the embedded/realtime world, so we would really appreciate support for them.

Thanks in advance for your time

I found comment in code:

// GPA Vk requires GFX8 or above (but also works on Hawaii) if (GDT_HW_GENERATION_VOLCANICISLAND > hwGen && GDT_HAWAII != cardInfo.m_asicType) { GPA_LogError("Hardware not supported."); }

I use southern islands gpu (r7 250) and spent my morning to find out that it's not even supported. Even though vulkan is working on that GPU (supported by driver).
