Subject: [PATCH 4/5] fbcon: Avoid hard-coding built-in font charcount

fbcon_startup() and fbcon_init() 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 `font->charcount`
instead of a hard-coded value.

This patch depends on patch "Fonts: Add charcount field to font_desc".
