Little-endian and other fixes for Broadcom XLP network driver
The changes are: - the microcore code loaded into the NAE has to be byteswapped in LE - the descriptors in memory for a P2P NAE descriptor has to be byteswapped in LE - the m_data pointer is already cacheline aligned, so the unnecessary m_adj to cacheline size can be removed - fix mask used to obtain physical address from the Tx freeback descriptor - fix a compile error in code under #ifdef Obtained from: Venkatesh J V <venkatesh.vivekanandan@broadcom.com>
