Earlier version of driver used direct io remapped register read writes using readl/writel. But we need secure boot access which is only possible when registers are read & written using regmap. This is because the security bus/hook is written & coupled only with regmap layer. Switch the driver from direct readl/writel based register accesses to regmap based register accesses. Additionally, update the license headers to latest status.
