Move xe driver from dev/pccard to dev/xe. Convert driver to newbus.
Driver is not functional yet, but does compile. Tests with xe cards indicates that it doesn't panic the machine when they are present, but fail to probe. Interface help in the pcic/pccard layers are needed to complete this driver.

/*
|
||||
* Register definitions for Xircom PCMCIA Ethernet controllers, based on
|
||||
* Rev. B of the "Dingo" 10/100 controller used in Xircom CEM56 and RealPort
|
||||
* Ethernet/modem cards. The Dingo can be configured to be register
|
||||
* compatible with the "Mohawk" 10/100 controller used in Xircom CE3 cards
|
||||
* (also some Intel and Compaq OEM versions of the CE3). The older 10Mbps CE2
|
||||
* cards seem to use earlier revisions of the same device. Some registers and
|
||||
* bits below are marked 'CE2 only'; these are used by Werner Koch's xirc2ps
|
||||
* driver that was originally for the CE2 but, according to the spec, aren't
|
||||
* present on the Dingo. They often seem to relate to operation on coax
|
||||
* cables, which Mohawk can do in theory (it has the SSI interface) so they
|
||||
* _might_ also work on Mohawk. I've also noted the few registers that are
|
||||
* specific to Dingo.
|
||||
*
|
||||
* As far as I can tell, the Dingo is basically a Mohawk device with a few
|
||||
* registers and support for a second PCMCIA function (the modem) added. In
|
||||
* Dingo mode the SSI (non-MII) PHY interface of the Mohawk is not available.
|
||||
* The CE2 chip is most likely a Mohawk without the MII and definitely with a
|
||||
* slightly different register set.
|
||||
*
|
||||
* In all cases, the controller uses a paged model of register access. The
|
||||
* first eight registers are always the same, the function of the second eight
|
||||
* is selected by the value in the Page Register (reg 0x01).
