mv643xx_eth: fix multicast filter programming
Commit 66e63ffbc04706568d8789cbb00eaa8ddbcae648 ("mv643xx_eth: implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter programming, but broke it as well. The non-special multicast filter table (for multicast addresses that are not of the form 01:00:5e:00:00:xx) consists of 256 hash table buckets organised as 64 32-bit words, where the 'accept' bits are in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word. The old code got this right, but the referenced commit broke this by using bits 3 2 1 0 instead. This commit fixes this up.
