[PATCH] hw/ppc/spapr: Include missing 'sysemu/tcg.h' header

[Philippe Mathieu-Daudé]

"sysemu/tcg.h" declares tcg_enabled(), and is implicitly included.
Include it explicitly to avoid the following error when refactoring
headers:

  hw/ppc/spapr.c:2612:9: error: call to undeclared function 'tcg_enabled'; ISO 
C99 and later do not support implicit function declarations 
[-Wimplicit-function-declaration]
    if (tcg_enabled()) {
        ^
