panfrost: Use packed TLS on Valhall
Packed TLS has cache-locality benefits on Valhall, compared to Bifrost's flat TLS. Valhall does support flat TLS, but requires extra arithmetic in the shader for correct results. At least until we get to generic pointers (and maybe even then), we can use packed TLS. So just use packed TLS always for proper spilling.
