[PATCH v4 1/2] arm: rmobile: Add PRR CPU ID macros for RZ/G2[HMNE]

[Biju Das]

RZ/G2 SoC's are identical to R-Car Gen3 SoC's apart from some
automotive peripherals and they also share the same PRR CPU ID's.

RZ/G2H (a.k.a R8A774E1) is identical to R-Car H3 SoC.
RZ/G2M (a.k.a R8A774A1) is identical to R-Car M3W SoC.
RZ/G2N (a.k.a R8A774B1) is identical to R-Car M3N SoC.
RZ/G2E (a.k.a R8A774C0) is identical to R-Car E3 SoC.

   * Dropped CPU info reporting logic for RZ/G2. Will address this later.
   * Added PRRID's for RZG2[HMNE]

 v2->v3  
   * Reworked as per Marek's suggestion
   * Added rzg2_get_cpu_type function to get cpu_type by matching TFA compatible string
   * Removed SoC family type Enum
