In the function ravb_hwtstamp_get() in ravb_main.c with the existing
values for RAVB_RXTSTAMP_TYPE_V2_L2_EVENT (0x2) and RAVB_RXTSTAMP_TYPE_ALL
(0x6)

if (priv->tstamp_rx_ctrl & RAVB_RXTSTAMP_TYPE_V2_L2_EVENT)
        config.rx_filter = HWTSTAMP_FILTER_PTP_V2_L2_EVENT;
else if (priv->tstamp_rx_ctrl & RAVB_RXTSTAMP_TYPE_ALL)
        config.rx_filter = HWTSTAMP_FILTER_ALL;

if the test on RAVB_RXTSTAMP_TYPE_ALL should be true, it will never
be reached. Correct this by changing RAVB_RXTSTAMP_TYPE_ALL to 0x4.

These macros are unused, we can safely drop them.

Cleanup only, no functional change.

    Don't mix fixes and cleanups in the same series, especially in the 
networking area -- the fixes are merged to the net.git repo and cleanups are 
merged to the net-next.git repo...
