In proc4430, ducati_destroy() is called from both proc4430_destroy() and
proc4430_stop().  Since ducati_setup() is called from proc4430_start(), the
call to ducati_destroy() in proc4430_destroy() is invalid.  It generates a
crash.

This patch adds the changes to Proc start and
Proc stop based on the validation on Zebu.
Proc start function is extended to enable M3
clock and program Ducati MMU. Proc Stop is extended
to put Cores in reset and disable M3 clock, and the
option to disable individual Core and MMU.

The memory alignment was not done properly in proc4430_map.  It was not
being aligned to the size of all pages needed to cover the reserved
area.  As a result, not all of it was reserved.  This has been fixed and
tested.

This patch provides the following functionality:
	1. Virt_To_Phys - Given a Co-processor's virtual
	address, the pages that are mapped are retured
	in the buffer passed by the user.
	2. Given a Chiron's virtual address, maps to
	Ducati virtual address. This is a hack for now
	to address Tiler memory until the dynmamic memory
	allocation for Tiler is supported.

	This patch also fixed bug in memory unmap function
	using iommu for Super and Large page cases.

The physical address of a memory entry is stored into the user
virtual address entry in proc4430_attach so that the user-side
can remap using this address in ProcMgrDrv_Open. The current mapping
uses the Slave address and assumes that the Slave address is same as
the physical address.

In proc manager open, the address translation (ducti -> mpu kernel,
ducati -> mpu user) were not populated from proc 4430 get info
function.
In this fix the adress translation tables are populated directly
from the proc instance handle memory entry tables in proc get info
function, rather than going in to proc4430 get info function for
the same. This fix is based on the approach followed in syslink code.

This patch adds proc4430 Attach and Detach functionality.
The Attach functions does ioremap of the Ducati physical
address, sets the slave virtual address same as the
physical address. This values are returned to the caller
in the params parameter passed to the Attach.
The Detach function does the reverse of Attach, where it
does the iounmap of the Master Virtual address.
Also, fixed the compile warning in procmgr.
