[PCMCIA] Drop level argument from pcmcia_socket_dev_* calls.
The driver model changed recently, and instead of providing per-driver
suspend/resume functionality, it now provides it on a per-bus basis.
It also dropped the "level" argument.
Unfortunately, platform device drivers suspend and resume methods
are no longer called by the driver model, so socket drivers using
platform devices won't work correctly. However, we fix them up as
best we can. (hd64465, i82365, sa1100, tcic)
This cset drops the `level' argument from the PCMCIA suspend/resume
functions since it is now meaningless.
