Add all the required code to program the GENET hardware to enter
Wake-on-LAN mode and wake using MagicPackets with or without SecureOn
password.

This code is hooked to the build system, but is not yet referenced from
ethtool or the main bcmgenet driver.

Attempt to the request the Wake-on-LAN interrupt bit, and if successful,
advertise wakeup capability instead of doing this unconditionnally.

Implement suspend/resume callbacks in the GENET driver. This makes sure
that we de-initialize and re-initialize the hardware correctly before
entering suspend and when resuming.

Introduce a bunch of helper functions: bcmgenet_netif_start,
bcmgenet_netif_stop and bcmgenet_intr_disable to help reuse code that is
going to be necessary for suspend/resume.

Factor the code touching the UniMAC RX/TX enable bits since we are going
to re-use it for implementing suspend/resume.

Checking for wol_enabled in bcmgenet_close() is bogus, since no other
code places set priv->wol_enabled. Remove that as it will conflict with
the upcoming and functional Wake-on-LAN implementation.

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

====================
drivers/net: remove unnecessary break after return

Second patchset after "remove unnecessary break after goto" addressing break redundancy on drivers/net branch
(suggested by Joe Perches)
