staging: cxt1e1: remove driver 

Remove the driver as it hasn't been cleaned up and it doesn't look like
anyone is going to work on it anymore. This can be reverted if someone
wants to work to fix the remaining issues the driver has.

config CXT1E1
tristate "SBE wanPMC-C[421]E1T1 hardware support"
depends on HDLC && PCI
---help---
This driver supports the SBE wanPMC-CxT1E1 1, 2 and 4 port T3
channelized stream WAN adapter card which contains a HDLC/Transparent
mode controller.
If you want to compile this driver as a module say M here.
The module will be called 'cxt1e1'.
If unsure, say N.
config SBE_PMCC4_NCOMM
bool "SBE PMCC4 NCOMM support"
depends on CXT1E1
---help---
SBE supplies optional support for NCOMM products.
If you have purchased this optional support you must say Y
here to allow the driver to operate with the NCOMM product.
