drivers: bus: Move the OMAP interconnect driver to drivers/bus/

OMAP interconnect drivers are used for the interconnect error handling.
Since they are bus driver, lets move it to newly created drivers/bus.

-/*
- * Interrupt Handler for L3 error detection.
- *	1) Identify the L3 clockdomain partition to which the error belongs to.
- *	2) Identify the slave where the error information is logged
- *	3) Print the logged information.
- *	4) Add dump stack to provide kernel trace.
- *
- * Two Types of errors :
- *	1) Custom errors in L3 :
- *		Target like DMM/FW/EMIF generates SRESP=ERR error
- *	2) Standard L3 error:
- *		- Unsupported CMD.
- *			L3 tries to access target while it is idle
- *		- OCP disconnect.
- *		- Address hole error:
- *			If DSS/ISS/FDIF/USBHOSTFS access a target where they
- *			do not have connectivity, the error is logged in
- *			their default target which is DMM2.
- *
- *	On High Secure devices, firewall errors are possible and those
- *	can be trapped as well. But the trapping is implemented as part
- *	secure software and hence need not be implemented here.
