drivers: rockchip: define more OTP indexes

The OTP area contains other values in addition to the HW_UNIQUE_KEY. For
example, the SECURE_BOOT_STATUS and the RSA_HASH, which are used by the
ROM code to verify booted images, are located there as well.

Define the index (in 32 bit words) and length (in 32 bit words) of these
values, too, to allow applications to read and write these locations.
