[PATCH v2 4/9] hw/arm: Include missing 'exec/tswap.h' header

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

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/arm/boot.c:175:19: error: call to undeclared function 'tswap32'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    175 |         code[i] = tswap32(insn);
        |                   ^
  hw/arm/npcm7xx.c:326:26: error: call to undeclared function 'tswap32'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    326 |         board_setup[i] = tswap32(board_setup[i]);
        |                          ^
