[PATCH] fonts: fixup font.h kernel-doc warnings

[Randy Dunlap <rdunlap@infradead.org>]

Use the typedef keyword when describing a typedef.
Add the missing function return value for font_glyph_size().

Warning: include/linux/font.h:84 cannot understand function prototype:
  'typedef const unsigned char font_data_t;'
Warning: include/linux/font.h:53 No description found for return value
  of 'font_glyph_size'
