ar71xx: ag71xx: make switch register access atomic

Reading of the PHY registers occasionally returns with bogus values
under heavy load. This misleads the PHY driver and thus causes false
link/speed change notifications which leads to performance loss.
This is easily noticable during an iperf session:

ar71xx: ag71xx: fix section mismatch warnings
...
The function __devinit ag71xx_probe() references
a function __devexit ag71xx_phy_disconnect().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
ag71xx_phy_disconnect() so it may be used outside an exit section.
The function ag71xx_phy_disconnect() references a function in an exit
section.
Often the function ag71xx_ar7240_cleanup() has valid usage outside the
exit section
and the fix is to remove the __devexit annotation of
ag71xx_ar7240_cleanup.

ar71xx: fix up alignment handling
...
- on ar724x, rx buffers can be aligned with an offset of 2, which keeps the ip header aligned
- alignment offset is only added if the ar8216 workaround is not active and the phy driver does not advertise its own packet alignment
- ar71xx and ar91xx can not handle rx alignment offsets, however taking a hit on unaligned exceptions seems to have less overhead than re-aligning the data for large packets
- use memmove to re-align small packets, if necessary
tested on ar9132, ar7240 and ar7242 based devices without ar8216 headers

Ag71xx needs to call the phy's netif_receive_skb() to allow phy drivers

This fixes the header mangling of the AR8216 driver.
