m68k/nommu: prevent setting ROMKERNEL when ROM is not set

Browse source 
When CONFIG_ROMKERNEL is set but CONFIG_ROM is not set, the linker
complains:
  m68k-linux-ld:./arch/m68k/kernel/vmlinux.lds:5: undefined symbol `CONFIG_ROMSTART' referenced in expression

# CONFIG_ROM is not set

CONFIG_ROMKERNEL=y

Since ROMSTART depends on ROM, make ROMKERNEL also depend on ROM.
