x86, realmode: fix 64-bit wakeup sequence There were number of issues in wakeup sequence: - Wakeup stack was placed in hardcoded address. - NX bit in EFER was not enabled. - Initialization incorrectly set physical address of secondary_startup_64. - Some alignment issues. This patch fixes these issues and in addition: - Unifies coding conventions in .S files. - Sets alignments of code and data right.
