xpp: start migration from procfs to sysfs.
* Sysfs representation for XPDs:
/sys/bus/xpds/devices/<bus>:<unit>:<subunit>
* Astribanks sysfs directories now include the XPDs as subdirectories:
e.g. /sys/bus/astribanks/devices/xbus-00/00:3:0
* procfs control interface deprecated: conditioned by OLD_PROC
(defaults to off). Control functionality moved to sysfs:
* xbus attributes: cls connector label status timing waitfor_xpds xbus_state
* XPDs can have driver-specific attributes. Common attriubtes:
blink chipregs span
* PRI-specific attributes:
pri_clocking pri_dchan pri_cas pri_alarms pri_layer1 pri_localloop pri_protocol
* The Astribank attribute "xbus_state" is read/write. Reading it shows
the current state of the Astribank. Writing "start" or "stop" allows a
software equivalent of connect or disconnect respectively.
* When an Astribank is ready it sends an "online" event. Whenever its
not ready (e.g. at the time of disconnect) it sends an "offline" event.
Use astribank_hook.sample to handle those.
