ARM: OMAP2+: hwmod: add support for lock and unlock hooks
Some IP blocks like RTC, needs an additional setting for writing to its registers. This is to prevent any spurious writes from changing the register values. This patch adds optional lock and unlock function pointers to the IP block's hwmod data. These unlock and lock function pointers are called by hwmod code before and after writing sysconfig registers.
