sparc: Use shared font data

Browse source

sparc has a 'btext' font used for the console which is almost identical
to the shared font_sun8x16, so use it rather than duplicating the data.

They were actually identical until about a decade ago when
   commit bcfbeecea1 ("drivers: console: font_: Change a glyph from
                        "broken bar" to "vertical line"")

which changed the | in the shared font to be a solid
bar rather than a broken bar.  That's the only difference.

This was originally spotted by PMD which noticed that PPC does
the same thing with the same data, and they also share a bunch
of functions to manipulate the data.

Tested very lightly with a boot without FS in qemu.
