arch/x86: Only use .bss from car.ld when running XIP

Some platform run early stages like romstage and verstage from CAR
instead of XIP. This allows to link them like other arch inside the
_program region. This make in place LZ4 decompression possible as it
needs a bit of extra place to extract the code which is now provided by
the .bss.

Tested on up/squared (Intel APL) & google/vilboz (AMD Picasso).
