[parisc-linux] EISA support

Hi Tom,

Similar for 720. Here i got the message:

Mongoose EISA Adapter found at 0xfc000000

An IBM Auto 16/4 Token Ring card is recognized, but doesn't work (instead, 
i randomly get a stack dump during the module load).

Another comment:

parisc_ksyms.c is missing the exports for memcpy_toio and memcpy_fromio.

Cheers,
Jochen
