This is a standalone patch for the hardware semaphore feature for
all brcmstb SoCs that have the same hardware semaphore registers
hence platform driver compatible uses:
	  '.compatible = "brcm,brcmstb-hwspinlock"'

The patch has been tested to work as builtin as well as a module.

v2 changes:
Adressed following review comments:
 - fixed ordering of obj brcmstb_hwspinlock.o in Makefile 
 - fixed ordering of 'config HWSPINLOCK_BRCMSTB' block in Kconfig
 - Renamed BRCMSTB_MAX_SEMAPHORES to BRCMSTB_NUM_SEMAPHORES
 - Removed unecessary platfrom_set_drvdata(pdev, bank);

Also addressing duplicate PATCH 1/3 sent in error as part of v1 change.
