      Phandle to the system General Purpose Register controller that contains
      WEIM CS GPR register, e.g. IOMUXC_GPR1 on i.MX6Q. IOMUXC_GPR1[11:0]
      should be set up as one of the following 4 possible values depending on
      the CS space configuration.

      IOMUXC_GPR1[11:0]    CS0    CS1    CS2    CS3
      ---------------------------------------------
              05          128M     0M     0M     0M
              033          64M    64M     0M     0M
              0113         64M    32M    32M     0M
              01111        32M    32M    32M    32M

      In case that the property is absent, the reset value or what bootloader
      sets up in IOMUXC_GPR1[11:0] will be used.

How about defining that the General Purpose Registers property is
once, rather than per device which needs access to it?
