powerpc: Use shared font data

PowerPC 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 bcfbeec ("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 the PMF source code analyser, which noticed that sparc does the same thing with the same data, and they also share a bunch of functions to manipulate the data. I've previously posted a near identical patch for sparc. Tested very lightly with a boot without FS in qemu.
