staging: Add driver to support wanPMC-CxT1E1 card.

Obviously still needs serious attention, but it compiles.

Original author: Rick Dobbs

Add driver to support wanPMC-CxT1E1 card.

This card provides 1-4 ports of T1E1 in PMC form factor.

Note, Rick doesn't want his email showing up as the "From:" author, but
has given his blessing to have the code included in the kernel tree.
