parisc/sticore: Avoid hard-coding built-in font charcount
sti_select_fbfont() and sti_cook_fonts() are hard-coding the number of
characters of our built-in fonts as 256. Recently, we included that
information in our kernel font descriptor `struct font_desc`, so use
`fbfont->charcount` instead of hard-coded values.
Depends on patch "Fonts: Add charcount field to font_desc".
