I'm committing this patch, which adds two bus drivers: bf52x and bf53x.
They are generic drivers. So they can be used for custom boards based on
bf52x and bf53x.

* src/bus/bf537_stamp.c (bus_params_t): Add aoe.
(AOE): Define.
(bf537_stamp_bus_new): Deal with ADDR[n], DATA[n] and AOE_B.
(bf537_stamp_bus_read_start): Assert AOE.
(bf537_stamp_bus_read_end): Deassert AOE.
(bf538f_ezkit_bus, bf526_ezkit_bus): Modify descriptions.
(urj_bus_bf52x_bus, urj_bus_bf53x_bus): Define.
* src/bus/buses.c (bus_drivers[]): Add urj_bus_bf52x_bus and
urj_bus_bf53x_bus.
* src/bus/buses_list.h: Add bf52x and bf53x.
* configure.ac: Add bf52x and bf53x bus drivers.
