U-Boot x86: Avoid clearing the VESA display

This is a patch from Simon Glass. U-Boot clears the display
when it starts up, but was asking the VESA driver to do the
same, needlessly; this patch avoids the latter.

A further patch is also included, which provides a better
message when jumping into long mode on the SPL (64-bit) target,
dumping it on the serial console instead of using printf.
