Use "select"s to ensure that the required kconfig symbols are set
as expected.
Drop HOSTAUDIO since it is now equivalent to UML_SOUND.
Allow SOUND with UML regardless of HAS_IOMEM. Otherwise there is a
kconfig warning for unmet dependencies. (This was not an issue when
SOUND was defined in arch/um/drivers/Kconfig. I have done 50 randconfig
builds and didn't find any issues.)
This fixes build errors when CONFIG_SOUND is not set:
ld: arch/um/drivers/hostaudio_kern.o: in function `hostaudio_cleanup_module':
hostaudio_kern.c:(.exit.text+0xa): undefined reference to `unregister_sound_mixer'
ld: hostaudio_kern.c:(.exit.text+0x15): undefined reference to `unregister_sound_dsp'

and this kconfig warning:

v2: don't delete the HOSTAUDIO Kconfig entry (Masahiro)
v3: drop HOSTAUDIO and use CONFIG_UML_SOUND for it in Makefile (Takashi);
add SOUND depends on "|| UML" to HAS_IOMEM

This option enables UML sound support. If enabled, it will pull in
soundcore and the UML hostaudio relay, which acts as a intermediary
between the host's dsp and mixer devices and the UML sound system.
It is safe to say 'Y' here.

If you have a sound card in your computer, i.e. if it can say more
than an occasional beep, say Y.
