get_bios_ebda_length() uses min_t() without including linux/kernel.h.
This may result in build errors with some configurations. Since the
function is not used anywhere in the kernel, let's just drop it.

Make the comments a bit clearer for get_bios_ebda so that it actually
tells us what it is returning.

Add a wrapper routine that tells us the length of the EBDA if it is
present. This guy also ensures that the returned length doesn't let the
EBDA run past the 640KiB mark.

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
