It's the result of me deciding CONFIG_XIP_ROM wasn't totally appropriate ...

... so I renamed it to CONFIG_XIP_KERNEL. Especially since there is also
XIPable user space which also can be stored in ROM (or flash). So please
disregard CONFIG_XIP_ROM and use CONFIG_XIP_KERNEL. Whether ROM or Flash is
used is rather irrelevant to the code this option is linked to.
