cpu/x86: don't treat all chipsets the same regarding XIP_ROM_SIZE
Previously, the XIP_ROM_SIZE Kconfig variable is used globally on x86 platforms with the assumption that all chipsets utilize this value. For the chipsets which do not use the variable it can lead to unnecessary alignment constraints in cbfs for romstage. Therefore, allow those chipsets a path to not be burdened by not passing '-P $(XIP_ROM_SIZE)' to cbfstool when adding romstage.
