[PATCH] bcm63xx: fix build failures when CONFIG_PCI is disabled

[Florian Fainelli <florian@openwrt.org>]

This patch fixes multiple build failures when CONFIG_PCI
is disabled. Since bcm63xx_sprom depends on CONFIG_SSB_PCIHOST
to be set, which depends on CONFIG_PCI, bcm63xx_sprom
would be unused thus causing this direct warning treated
as an error:

cc1: warnings being treated as errors
arch/mips/bcm63xx/boards/board_bcm963xx.c:466: warning: 'bcm63xx_sprom' defined but not used

Then bcm63xx_pci_enabled would not be resolved since it
is declared in arch/mips/pci/pci-bcm63xx.c which is not
compiled due to CONFIG_PCI being disabled. Finally,
ssb_set_arch_fallback would not be resolved too, since
CONFIG_SSB_PCIHOST is disabled.
