powerpc: Fix build break with PPC_EARLY_DEBUG_BOOTX=y
A kernel configured with PPC_EARLY_DEBUG_BOOTX=y but PPC_PMAC=n and PPC_MAPLE=n will fail to link: btext.c:(.text+0x2d0fc): undefined reference to `.rmci_off' btext.c:(.text+0x2d214): undefined reference to `.rmci_on' Fix it by making the build of rmci_on/off() depend on PPC_EARLY_DEBUG_BOOTX, which also enable the only code that uses them.
