[PULL 7/7] m68k: import bootinfo headers from linux

[Laurent Vivier <laurent@vivier.eu>]

Copy bootinfo.h and bootinfo-mac.h from arch/m68k/include/uapi/asm/
to include/standard-headers/asm-m68k/

Imported from linux v5.9 but didn't change since v4.14 (header update)
and since v4.10 (content update).
