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).
