bcma: add mips driver This adds a mips driver to bcma. This is only found on embedded devices. For now the driver just initializes the irqs used on this system.

bcma: fix bcm4716/bcm4748 i2s irqflag The default irqflag assignment for the I2S core on some Broadcom 4716/4748 devices is invalid and needs to be corrected (from the Broadcom SDK).

bcma: just do the necessary things in early register on SoCs Some parts of the initialization for chip common and the pcie core are accessing the sprom struct, but it is not initialized at that stage. Just do the necessary thing in the early register on SoCs and not the complete initialization to read out the nvram from the flash chip. After it is possible to read out the nvram, the sprom should be parsed from it and the full initialization of the cores should be run.
