x86: Save the BIST value on reset
The built in self test value is available in register eax on start-up. Save
it so that it can be accessed later. Unfortunately we must wait until the
global_data is available before we can do this, so there is a little bit of
shuffling to keep it around.

x86: Use the standard arch_cpu_init() function
Instead of an x86-specific cpu_init_f() function, use the normal U-Boot one
for this purpose. Also remove a useless/misleading comment.

x86: Tidy up global descriptor table setup
This code is a little muddled, so tidy it up. Make sure that we put the
GDT in the right place and set it up properly.

x86: Invalidate TLB as early as possible
We should invalidate the TLB right at the start to ensure that we don't get
