Thomas Cort 4593804bf0 kernel: add padconf kernel call
On the AM335X, writes to the padconf registers must be done in privileged
mode. To allow userspace drivers to dynamically change the padconf at
runtime, a kernel call has been added.

/* Function prototypes for the system library. The prototypes in this file
* are undefined to NULL if the kernel call is not enabled in config.h.
* The implementation is contained in src/kernel/system/.
*
* The system library allows to access system services by doing a kernel call.
* System calls are transformed into request messages to the SYS task that is
* responsible for handling the call. By convention, sys_call() is transformed
* into a message with type SYS_CALL that is handled in a function do_call().
*
* Changes:
* Mar 01, 2010 SYS_CLEAR and SYS_EXIT split (Cristiano Giuffrida)
* Jul 30, 2005 created SYS_INT86 to support BIOS driver (Philip Homburg)
* Jul 13, 2005 created SYS_PRIVCTL to manage services (Jorrit N. Herder)
* Jul 09, 2005 updated SYS_KILL to signal services (Jorrit N. Herder)
* Jun 21, 2005 created SYS_NICE for nice(2) kernel call (Ben J. Gras)
* Jun 21, 2005 created SYS_MEMSET to speed up exec(2) (Ben J. Gras)
* Jan 20, 2005 updated SYS_COPY for virtual_copy() (Jorrit N. Herder)
* Oct 24, 2004 created SYS_GETKSIG to support PM (Jorrit N. Herder)
* Oct 10, 2004 created handler for unused calls (Jorrit N. Herder)
* Sep 09, 2004 updated SYS_EXIT to let services exit (Jorrit N. Herder)
* Aug 25, 2004 rewrote SYS_SETALARM to clean up code (Jorrit N. Herder)
* Jul 13, 2004 created SYS_SEGCTL to support drivers (Jorrit N. Herder)
* May 24, 2004 created SYS_SDEVIO to support drivers (Jorrit N. Herder)
* May 24, 2004 created SYS_GETINFO to retrieve info (Jorrit N. Herder)
* Apr 18, 2004 created SYS_VDEVIO to support drivers (Jorrit N. Herder)
* Feb 24, 2004 created SYS_IRQCTL to support drivers (Jorrit N. Herder)
* Feb 02, 2004 created SYS_DEVIO to support drivers (Jorrit N. Herder)
