Added similar PM errata flag support as omap3 has. A few errata flags will be added in subsequent patches.
Considering that we might have erratas for future SoCs as well, should'nt we just set up a common errata flag for all SoCs and since we have i123 numbers, would it help being able to reuse errata flags cross SoC generations (if we need to)?
