bcma: don't leak memory for PCIE, MIPS, GBIT cores
bcma_scan_bus allocates a bcma_core for each core found on the bus, but the memory for cores handled by the bcma driver itself was not being freed when the bus was unregistered. This patch adds special handling for the PCIE, MIPS, and GBIT COMMON cores, to ensure that their memory allocation is freed as well. Note that this patch doesn't address the memory allocated for the CC core, as that was corrected in my previous patch "bcma: register cc core driver, device."
