staging: keucr: remove driver 

The driver hasn't been fully cleaned up and it doesn't look like anyone
is working on it anymore (including the original author). So remove the
driver and all references to it. If someone wants to finish cleaning
the driver up and moving it out of staging, this commit can be reverted.

config USB_ENESTORAGE
tristate "USB ENE SM card reader support"
depends on USB && SCSI && m
---help---
Say Y here if you wish to control a ENE SM Card reader.
To use SD/MS card, please build driver/usb/storage/ums-eneub6250.ko
This option depends on 'SCSI' support being enabled, but you
probably also need 'SCSI device support: SCSI disk support'
(BLK_DEV_SD) for most USB storage devices.
To compile this driver as a module, choose M here: the
module will be called keucr.

TODO:
- checkpatch.pl clean
- sparse clean
- determine if the driver should not be using a duplicate
version of the usb-storage scsi interface code, but should
be merged into the drivers/usb/storage/ directory and
infrastructure instead.
- review by the USB developer community
- smcommon.h & smilsub.c: use kernel hweight8(), hweight16()
Please send any patches for this driver to Al Cho <acho@novell.com> and
Greg Kroah-Hartman <gregkh@linuxfoundation.org>.

Say Y here if you wish to control a ENE SD/MS Card reader.
To use SM card, please build driver/staging/keucr/keucr.ko
Note that this driver does not support SM cards.
This option depends on 'SCSI' support being enabled, but you
probably also need 'SCSI device support: SCSI disk support'
