staging: unisys: visorbus: remove unused sysfs attribute devmajorminor/*
The sysfs attribute directory at:
/sys/bus/visorbus/devices/vbus<x>:dev<y>/devmajorminor/*
or
/sys/devices/visorbus<x>/vbus<x>:dev<y>/devmajorminor/*
previously provided a location where a visorbus function driver could
publish information (for usermode use) about possibly-multiple major and
minor device numbers for character devices created for a each visorbus
device, using visorbus_registerdevnode(). This functionality is not
currently used, so it has been removed by this cset.
