MIPS: BCM47xx: Support on-SoC bus in SPROM reading function
To support (extract) SPROM on Broadcom ARM devices we should separate SPROM code and make it a separated module. We won't want to export bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard fallback function and then modify ssb to use it.
