staging/solo6x10: depend on CONFIG_FONTS

The new SOLO6X10 driver needs the built-in console fonts, specifically
the VGA8x16 font and building it without console support results in
a link error error.

drivers/built-in.o: In function `solo_osd_print':
 :(.text+0x7d3424): undefined reference to `find_font'

This adds a dependency on the CONFIG_FONTS symbol and changes the
console code to always build the base driver even if there are
no specific fonts built-in.
