[PATCH v2 5/9] hw/ppc: Include missing 'exec/tswap.h' header

[Philippe Mathieu-Daudé]

Some files indirectly get "exec/tswap.h" declarations via
"exec/cpu-all.h". Include it directly to be able to remove
the former from the latter, otherwise we get:

  hw/ppc/virtex_ml507.c:123:19: error: call to undeclared function 'tswap32'; 
ISO C99 and later do not support implicit function declarations 
[-Wimplicit-function-declaration]
    123 |     env->gpr[6] = tswap32(EPAPR_MAGIC);
        |                   ^
  hw/ppc/sam460ex.c:238:23: error: call to undeclared function 'tswap32'; ISO 
C99 and later do not support implicit function declarations 
[-Wimplicit-function-declaration]
    238 |         env->gpr[6] = tswap32(EPAPR_MAGIC);
        |                       ^
  hw/ppc/spapr.c:1617:13: error: call to undeclared function 'tswap64'; ISO C99 
and later do not support implicit function declarations 
[-Wimplicit-function-declaration]
   1617 |             DIRTY_HPTE(HPTE(spapr->htab, i));
        |             ^
  hw/ppc/spapr.c:1406:55: note: expanded from macro 'DIRTY_HPTE'
   1406 | #define DIRTY_HPTE(_hpte)  ((*(uint64_t *)(_hpte)) |= 
tswap64(HPTE64_V_HPTE_DIRTY))
        |                                                       ^
