x86: sta2x11: include header for sta2x11_get_instance() prototype

sta2x11_get_instance() is a global function declared in asm/sta2x11.h, but
this header is not included before the definition, causing a warning:

arch/x86/pci/sta2x11-fixup.c:95:26: error: no previous prototype for 'sta2x11_get_instance' [-Werror=missing-prototypes]

Add the missing #include.
