Subject: [PATCH 01/16] arch: x86: boot: Make function static and add function prototype

compressed/eboot.c defines an internal function
setup_graphics(struct boot_params *boot_params). No
other file refers to this function with the same
parameters so make this function static.

This eliminates the following warning:

arch/x86/boot/compressed/eboot.c:1004:6: warning: no previous prototype for ‘setup_graphics’ [-Wmissing-prototypes]

Also make_boot_params is declared only in this file and is used
in some assembly. So add a prototype for this function.

This eliminates the following warning:

arch/x86/boot/compressed/eboot.c:1042:21: warning: no previous prototype for ‘make_boot_params’ [-Wmissing-prototypes]
