irqchip/renesas-rzv2h: Add RZ/G3E support

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 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.

Add support for the RZ/G3E driver by filling the rzv2h_hw_info table and
adding LUT for mapping between pin index and TINT selection index.
