media: rzg2l-cru: Add support for RZ/G3E SoC

The CRU block on the Renesas RZ/G3E SoC is similar to the one found on
the Renesas RZ/G2L SoC, with the following differences:

- Additional registers rzg3e_cru_regs.
- A different irq handler rzg3e_cru_irq.
- A different rzg3e_cru_csi2_setup.
- A different max input width.
- Additional stride register.

Introduce rzg3e_cru_info struct to handle differences between RZ/G2L
and RZ/G3E and related RZ/G3E functions:

 - rzg3e_cru_enable_interrupts()
 - rzg3e_cru_enable_interrupts()
 - rz3e_fifo_empty()
 - rzg3e_cru_csi2_setup()
 - rzg3e_cru_get_current_slot()

Add then support for the RZ/G3E SoC CRU block with the new compatible
string "renesas,r9a09g047-cru".
