Subject: [PATCH 1/1] Fonts: font_acorn_8x8: Replace discarded const qualifier

Commit 09e5b3fd5672 ("Fonts: Support FONT_EXTRA_WORDS macros for
built-in fonts") introduced the following error when building
rpc_defconfig (only this build appears to be affected):

 `acorndata_8x8' referenced in section `.text' of arch/arm/boot/compressed/ll_char_wr.o:
    defined in discarded section `.data' of arch/arm/boot/compressed/font.o
 `acorndata_8x8' referenced in section `.data.rel.ro' of arch/arm/boot/compressed/font.o:
    defined in discarded section `.data' of arch/arm/boot/compressed/font.o
 make[3]: *** [/scratch/linux/arch/arm/boot/compressed/Makefile:191: arch/arm/boot/compressed/vmlinux] Error 1
 make[2]: *** [/scratch/linux/arch/arm/boot/Makefile:61: arch/arm/boot/compressed/vmlinux] Error 2
 make[1]: *** [/scratch/linux/arch/arm/Makefile:317: zImage] Error 2

The .data section is discarded at link time.  Reinstating
acorndata_8x8 as const ensures it is still available after linking.
