The LOCKSTATUS register for memory-mapped coresight devices indicates
whether or not the device in question implements hardware locking. If
not, locking is not present (i.e. LSR.SLI == 0) and LAR is write-ignore,
so software doesn't actually need to check the status register at all.
This patch removes the broken LSR checks.

OMAP4 uses cross trigger interface(CTI) to route
performance monitor irq to GIC, so introduce cti
helpers to make access for cti easily.
