Modified Files:
	src/sys/arch/amd64/acpi [jmcneill-pm]: acpi_wakeup.c acpi_wakeup_low.S

Log Message:
Change code flow below acpi_md_sleep.

Before:
- acpi_md_sleep calls acpi_savecpu
- acpi_savecpu saves registers and returns with -1
- acpi_md_sleep now patches the wakecode and calls AcpiEnterSleepState
- on resume, acpi_restorecpu restores registers and returns at the same
place as acpi_savecpu did with 0.

After:
- acpi_md_sleep calls acpi_md_sleep_prepare
- acpi_md_sleep_prepare saves registers and calls acpi_md_sleep_enter
- acpi_md_sleep_enter patches the wakecode and calls
AcpiEnterSleepState. It only returns on error.
- on resume, acpi_md_sleep_exit gets called, restores the registers and
returns as acpi_md_sleep_prepare with 0.
