Mike Waychison f548ccd47d x86: Better comments for get_bios_ebda()
Make the comments a bit clearer for get_bios_ebda so that it actually
tells us what it is returning.

Mike Waychison 57d5f9f808 x86: get_bios_ebda_length()
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.

H. Peter Anvin 1965aae3c9 x86: Fix ASM_X86__ header guards
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.
