x86, setup: Don't skip mode setting for the standard VGA modes

The code for setting standard VGA modes probes for the current mode,
and skips the mode setting if the mode is 3 (color text 80x25) or 7
(mono text 80x25). Unfortunately, there are BIOSes, including the
VMware BIOS, which report the previous mode if function 0F is queried
while the screen is in a VESA mode, and of course, nothing can help a
mode poked directly into the hardware.

As such, the safe option is to set the mode anyway, and only query to
see if we should be using mode 7 rather than mode 3. People who don't
want any mode setting at all should probably use vga=0x0f04
(VIDEO_CURRENT_MODE). It's possible that should be the kernel
default.

x86, setup: un-resequence mode setting for VGA 80x34 and 80x60 modes

Impact: Fixes these modes on at least one system

The rewrite of the setup code into C resequenced the font setting and
register reprogramming phases of configuring nonstandard VGA modes
which use 480 scan lines in text mode. However, there exists at least
one board (Micro-Star MS-7383 version 2.0) on which this resequencing
causes an unusable display.

Revert to the original sequencing: set up 480-line mode, install the
font, and then adjust the vertical end register appropriately.

This failure was masked by the fact that the 480-line setup was broken
until checkin 5f641356127712fbdce0eee120e5ce115860c17f (therefore this
is not a -stable candidate bug fix.)

Move wakeup code to .c, so that video mode setting code can be shared

re-using trampoline code. Stack setup was fixed to clear high 16bits
of %esp, maybe that fixes some machines.

reviewed kbuild related stuff, and it seems okay to him. Rafael did
some cleanups.

* Added arch/x86/kernel/acpi/sleep.h
* Got rid of compiler warnings in arch/x86/kernel/acpi/sleep.c
