Add pin controller support for the Renesas RZ/G3E(R9A09G047) SoC. The
RZ/G3E PFC is similar to the RZ/V2H SoC but has more pins(P00-PS3).
The port number on both RZ/V2H and RZ/G3E is alpha-numeric compared to
the number on the other SoCs. So added support for defining alpha-numeric
port names.

v3->v4:
 * Added new header file with separate RZV2H_P* and RZG3E_P* definitions.
 * Dropped ack tag from Conor for patch#2 as there is separate file for
   RZG3E_P* definitions.
 * Included header file renesas,r9a09g057-pinctrl.h
 * Updated r9a09g057_variable_pin_cfg table replacing PORT_PB->RZV2H_PB
   macro.
 * Included header file renesas,r9a09g047-pinctrl.h
 * Replaced macros PORT_P*->RZG3E_P* 
 * Updated rzg3e_gpio_names table with NULL port names for ports
   corresponding to unsupported hardware indices.
 * Updated r9a09g047_gpio_configs table with NULL value for ports
   corresponding to unsupported hardware indices.
 * Collected Rb tag from Geert for dts changes.
v2->v3:
 * Added alpha-numerical port name support to both RZ/V2H and RZ/G3E.
 * Added PORT_P* macros based on PFC_P_mn offset and RZ{G3E,V2H}_*
   macros for defining port names in DT.  
 * Collected tags.
 * Updated r9a09g057_variable_pin_cfg table replacing port 11 with PORT_PB.
 * Replaced macros WDTUDF_CA->WDTUDFCA and WDTUDF_CM->WDTUDFCM.
 * Replaced macro QSD0_*->SD0*.
 * Updated gpio range from 176->232 to match the port number based
   on hardware indices.
v1->v2:
 * Updated typo of the patch header RZ/G2L->RZ/G3E
 * Fixed the binding warnings reported by bot.
