x86: Don't relocate symbols which point to things that aren't relocated
This change adds an upper bound for symbols which are fixed up after u-boot
is relocated into RAM. This way portions that are left at their original
location can be referred to without having to manually fix up any pointers.

x86: Fix how the location of the realmode and bios blobs are calculated
There are two blobs embedded into the u-boot image which are linked to run
at an address which is different from where they actually end up in the
ROM, one called "realmode" and one called "bios". There are realmode_setup
and bios_setup functions which prepare those blobs by copying them into the
location they're supposed to run from, among other things.
During u-boot relocation from ROM to RAM, the text and a few data segments
are copied over. The realmode and bios sections are not copied, and so the
only place they can be read from is their original location in the ROM.
Looking specifically at the bios blob, there are symbols defined in the
linker script called __bios_start and __bios_size which are defined to be
the start and size of the blob in the ROM.
In the bios_setup function, there seem to be two mistakes happening. First,
the offset from ROM to RAM is being added to __bios_start which implies that
this code expects to use the copy moved to RAM. No such copy is made, so
that's wrong. More subtly, when u-boot relocates itself, it goes through
all of the relocations stored in .rel.dyn and fixes them up. This has the
effect of transforming the __bios_start reference in bios_setup so that it
refers to the version in RAM (if one existed) instead of the one in ROM. To
correct for that, the offset actually needs to be subtracted out again to
translate the address back into the ROM.
The net effect is that for both blobs, a + needs to be changed to a -.

menu.c: use puts() instead of printf() where possible
common/menu.c used printf() in a number of places to print user
provided, constant strings (like the "title" string). printf() is
dangerous here for example in case the user unwittingly embeds some
'%' caracters that printf() would interpret as formatting and then
pick up random arguments. Use puts() instead.
We also omit the trailing ':' in the title line - if a user wants
this, he can provide it as part of the title string.

doesn't obey the power ramp up process in the SD specification 6.4.1.
(Please refer to figure 6.1 and 6.2 in the specification.)
The CMD0 should be send after power ramp up has been finished.
However, the Marvell mmc contorller must do power ramp up after the
