David Brownell 7dac6f8df6 net/enc28j60: low power mode
Keep enc28j60 chips in low-power mode when they're not in use.
At typically 120 mA, these chips run hot even when idle; this
low power mode cuts that power usage by a factor of around 100.

This version provides a generic routine to poll a register until
its masked value equals some value ... e.g. bit set or cleared.
It's basically what the previous wait_phy_ready() did, but this
version is generalized to support the handshaking needed to
enter and exit low power mode.

David Brownell 6fd65882f5 net/enc28j60: section fix
Minor bugfixes to the enc28j60 driver ... wrong section marking,
indentation, and bogus use of spi_bus_type.

David Brownell 02ff05c49d net/enc28j60: oops fix
Prevent oops on enc28j60 packet RX:  make sure buffers are aligned.
Not all architectures support unaligned accesses in kernel space.
