[PATCH 07/78] wl18xx: add some boot operations and hw-specific configurations

[Arik Nemtsov <arik@wizery.com>]

From: Luciano Coelho <coelho@ti.com>

Implement the boot operation.  Add a wl18xx-specific configuration
structure (namely to configure the mac and phy parameters).

The default hw configuration matches the DVP board.
