sys/dev: further adoption of SPDX licensing ID tags.

2017-11-27T14:52:40Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Consistently use `device_t`

2016-08-09T19:32:06Z

Several files use the internal name of `struct device` instead of `device_t` which is part of the public API. This patch changes all `struct device *` to `device_t`. The remaining occurrences of `struct device` are those referring to the Linux or OpenBSD version of the structure, or the code is not built on FreeBSD and it's unclear what to do.

Enroll these drivers in multipass probing. The motivation behind this

2009-12-22T21:02:46Z

is that the JBus to EBus bridges share the interrupt controller of a sibling JBus to PCIe bridge (at least as far as the OFW device tree is concerned, in reality they are part of the same chip) so we have to probe and attach the latter first. That happens to be also the case due to the fact that the JBus to PCIe bridges appear first in the OFW device tree but it doesn't hurt to ensure the right order.

- Only touch the LED bit of the (LED) AUXIO register when turning the

system LED on or off. Unlike the EBus LED AUXIO register where the remaining bits are unused the upper bits of the SBus AUXIO register are used to control other things like the link test enable pin of the on-board NIC which we don't want to change as a side-effect. - Remove the superfluous bzero()'ing of the softc obtained from device_get_softc().

Switch from trying to allocate up to 8 register banks for the EBus
