pcmcia: remove unused pxa/sa1100 drivers 

A number of boards got removed, so this code is now orphaned.

* BadgePAD 4 Details
*
* PCM Vcc:
*
* PCM Vcc on BadgePAD 4 can be jumpered for 3v3 (short pins 1 and 3
* on JP6) or 5v0 (short pins 3 and 5 on JP6).
*
* PCM Vpp:
*
* PCM Vpp on BadgePAD 4 can be jumpered for 12v0 (short pins 4 and 6
* on JP6) or tied to PCM Vcc (short pins 2 and 4 on JP6). N.B.,
* 12v0 operation requires that the power supply actually supply 12v0
* via pin 7 of JP7.
*
* CF Vcc:
*
* CF Vcc on BadgePAD 4 can be jumpered either for 3v3 (short pins 1
* and 2 on JP10) or 5v0 (short pins 2 and 3 on JP10).
*
* Unfortunately there's no way programmatically to determine how a
* given board is jumpered. This code assumes a default jumpering
* as described below.
*
* If the defaults aren't correct, you may override them with a pcmv
* setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
* tenths of volts; e.g. pcmv=33,120,50 indicates 3v3 PCM Vcc, 12v0
* PCM Vpp, and 5v0 CF Vcc.
