x86: remove extern declarations for code, data, bss resources

This patch removes the extern struct resource declarations for
data_resource, code_resource and bss_resource on x86 and declares that
three structures as static as done on other architectures like IA64.

On i386, these structures are moved to setup_32.c (from e820_32.c) because
that's code that is not specific to e820 and also required on EFI systems.
That makes the "extern" reference superfluous.

On x86_64, data_resource, code_resource and bss_resource are passed to
e820_reserve_resources() as arguments just as done on i386 and IA64.  That
also avoids the "extern" reference and it's possible to make it static.
