This patch sets the port mode to MII when the link is down for the 5785.
Setting the port mode to MII instead of GMII saves power.

The AC131 does not respect the power down bit (bit 11) of the MII
Control Register (reg 0x0).  Instead, software is required to put the
phy into standby power down mode through the shadow register set.  This
patch implements support for the AC131 standby power down mode.

Manually inline the code from bond_deinit to bond_uninit.  bond_uninit
is the only caller and it is short.

Move the call of bond_release_all from the netdev notifier into
bond_uninit.  The call site is effectively the same and performing
the call explicitly allows all the paths for destroying a
bonding device to behave the same way.

The CAPI interface incorrectly assumed that CAPI messages would always
start at the beginning of the data buffer: fix by treating DATA_B3
messages as the link layer header to their payload data. This fix
changes the way acknowledgement information is propagated through the
hardware specific modules and thereby impacts the ISDN4Linux variant
of the driver, too.

Also some assumptions about methods not being called from interrupt
context turned out to be unwarranted; fix by using dev_kfree_skb_any()
wherever non-interrupt context isn't guaranteed.
