net: bgmac: fix BCM5358 support by setting correct flags
commit d61615c366a489646a1bfe5b33455f916762d5f4 upstream. Code blocks handling BCMA_CHIP_ID_BCM5357 and BCMA_CHIP_ID_BCM53572 were incorrectly unified. Chip package values are not unique and cannot be checked independently. They are meaningful only in a context of a given chip. Packages BCM5358 and BCM47188 share the same value but then belong to different chips. Code unification resulted in treating BCM5358 as BCM47188 and broke its initialization.
