 * CSR9000 - 802.11bgn (non HT40), bluetooth, FM RX/TX

Driver
staging: csr: remove driver This driver is not being updated as the specifications are not able to be gotten from CSR or anyone else. Without those, getting this driver into proper mergable shape is going to be impossible. So remove the driver from the tree.
 * Driver for CSR60xx was remove from driver/staging after kernel 3.10

If the specifications ever become available, this patch can be reverted and the driver fixed up properly.
