x86: Make ROM_SIZE configurable in Kconfig

Browse source 
Currently the ROM_SIZE is hardcoded to 8MB in arch/x86/Kconfig. This
will not be the case when adding additional board support. Hence we
make ROM_SIZE configurable (512KB/1MB/2MB/4MB/8MB/16MB) and have the
board Kconfig file select the default ROM_SIZE.
