[2.6 patch] drivers/usb/misc/ftdi-elan.c: fixes and cleanups

[Adrian Bunk <bunk@stusta.de>]

This patch contains the following possible cleanups:
- make the needlessly global ftdi_release_platform_dev() static
- remove the unused usb_ftdi_elan_read_reg()
- proper prototypes for the following functions:
  - usb_ftdi_elan_read_pcimem()
  - usb_ftdi_elan_write_pcimem()

Note that the misplaced prototypes for the latter ones in 
drivers/usb/host/u132-hcd.c were buggy. Depending on the calling 
convention of the architecture calling one of them could have turned 
your stack into garbage.

 /*
 * these can not be inlines because we need the structure offset!!
 * Does anyone have a better way?????
