You can just use:
depends on VIDEO_CX88_DVB_MT352

VIDEO_CX88_DVB_MT352 already pulls in the !VIDEO_CX88_DVB_ALL_FRONTENDS
for you, as well VIDEO_CX88_DVB and so on.

This patch solves the problem just fine.  As I understand it, what you are
doing is creating VIDEO_CX88_DVB_VP3054 as a proxy for VIDEO_CX88_VP3054, and
making it so VIDEO_CX88_VP3054 isn't set directly by the user, but rather via
VIDEO_CX88_DVB_VP3054.  This way VIDEO_CX88_VP3054 doesn't depend _directly_
on VIDEO_CX88_DVB_MT352, but depends on it via the VIDEO_CX88_DVB_VP3054
proxy, which kconfig can now display correctly.  I don't understand why this
indirection is necessary, but it works, and that's enough for me.
