MMU memory management subsystem.

  arm/mpu: Provide access to the MPU region from the C code
  arm/mpu: Introduce utility functions for the pr_t type
  arm/mpu: Provide a constructor for pr_t type
  arm/mpu: Introduce MPU memory mapping flags
  arm/mpu: Implement early_fdt_map support in MPU systems
  arm/mpu: Implement setup_mappings for MPU system

Penny Zheng (2):
