[PCMCIA] Add, fix, update PCMCIA debugging. 

The PCMCIA core debugging assumes that "pc_debug" is a global.  If
pc_debug were to be a global, it would pollute the kernel's global
name space, potentially clashing with PCMCIA drivers and even ds.c.
 
We also get rid of PCMCIA using the "DEBUG" macro, which is the
standard macro to enable debugging in the kernel.  Instead, we
introduce cs_dbg() for core PCMCIA debugging, ds_dbg() for driver
services debugging, and similar macros in the socket drivers.

help
Say Y here to enable PCMCIA subsystem debugging. You
will need to choose the debugging level either via the
kernel command line, or module options depending whether
you build the PCMCIA as modules.
The kernel command line options are:
pcmcia_core.pc_debug=N
ds.pc_debug=N
sa11xx_core.pc_debug=N
The module option is called pc_debug=N
In all the above examples, N is the debugging verbosity
level.
