====================
ioc3-eth improvements

In my patch series for splitting out the serial code from ioc3-eth
by using a MFD device there was one big patch for ioc3-eth.c,
which wasn't really usefull for reviews. This series contains the
ioc3-eth changes splitted in smaller steps and few more cleanups.
Only the conversion to MFD will be done later in a different series.

Changes in v3:
- no need to check skb == NULL before passing it to dev_kfree_skb_any
- free memory allocated with get_page(s) with free_page(s)
- allocate rx ring with just GFP_KERNEL
- add required alignment for rings in comments

Changes in v2:
- use net_err_ratelimited for printing various ioc3 errors
- added missing clearing of rx buf valid flags into ioc3_alloc_rings
- use __func__ for printing out of memory messages
