pcmcia: remove Pin, Copy configuration register access

The "Pin" and "Copy" configuration registers (CISREG_SCR, CISREG_PPR)
do not seem to be utilized anywhere. If a device would request a
write to these registers, "0" would be written. Continue to do so, but
warn of unexpected behavior -- and remove the "Pin" and "Copy" entries
from config_req_t.
