Document RZ/G3E (R9A09G047) ICU bindings. The ICU block on the RZ/G3E
SoC is almost identical to the one found on the RZ/V2H SoC, with the
following differences:
 - The TINT register base offset is 0x800 instead of zero.
 - The number of supported GPIO interrupts for TINT selection is 141
   instead of 86.
 - The pin index and TINT selection index are not in the 1:1 map
 - The number of TSSR registers is 16 instead of 8
 - Each TSSR register can program 2 TINTs instead of 4 TINTs

Hence new compatible string "renesas,r9a09g047-icu" is added for RZ/G3E
SoC.
