drivers: hwspinlock: add framework Add a platform-independent hwspinlock framework. Hardware spinlock devices are needed, e.g., in order to access data that is shared between remote processors, that otherwise have no alternative mechanism to accomplish synchronization and mutual exclusion operations.

hwspinlock/core: simplify Kconfig Simplify hwspinlock's Kconfig by making the global CONFIG_HWSPINLOCK entry invisible; users will just select it when needed. This also prepares the ground for adding hwspinlock support for other platforms (the 'depends on ARCH_OMAP4' was rather hideous, and while we're at it, a dedicated menu is added).

hwspinlock: enable OMAP build for AM33xx, AM43xx & DRA7xx HwSpinlocks are supported on TI's AM33xx, AM43xx and DRA7xx SoC device families as well. The IPs are identical to that of OMAP4/OMAP5, except for the number of locks. Add a depends on to the above family of SoCs to enable the build support for OMAP hwspinlock driver for any of the above SoC configs.
