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.
