The SAP in LS102x SoC's from Freescale is able to read and write to all
physical memory locations, independently of CPU cores and DAP.

This implementation is 100% based on reverse-engineering of JTAG
communication with an LS1021A SAP using a JTAG debugger with SAP support.

And as such, this code is for now "works-for-me", pending verification
by other OpenOCD users, or even better, actual information from Freescale
on the SAP interface.
