[PATCH v2] mos6522: fix linking error when CONFIG_MOS6522 is not set

[PATCH v2] mos6522: fix linking error when CONFIG_MOS6522 is not set

[Murilo Opsfelder Araujo]

When CONFIG_MOS6522 is not set, building ppc64-softmmu target fails:

    /usr/bin/ld: libqemu-ppc64-softmmu.fa.p/monitor_misc.c.o:(.data+0x1158): undefined reference to `hmp_info_via'

Make devices configuration available in hmp-commands*.hx and check for
CONFIG_MOS6522.

Fixes: 409e9f7131e5 (mos6522: add "info via" HMP command for debugging)

I think you could even get rid of the TARGET_ stuff now that the CONFIG line 
works!

Looks reasonable to me.

So with the "#if defined(TARGET_M68K) || defined(TARGET_PPC)" removed:

I've sent v3 with your suggestion:

     https://lore.kernel.org/qemu-devel/20220510235439.54775-1-muriloo@linux.ibm.com/

Thank you for your review.
