Hi All,

This patch series adds support for the Renesas RZ/N2H (R9A09G087) SoC and
the RZ/N2H EVK (R9A09G087M44-RZN2H-EVK) evaluation board. The RZ/N2H SoC
is very much similar to the RZ/T2H (R9A09G077) SoC. 

RZ/N2H is a high-performance MPU that delivers advanced application
processing and real-time operation for industrial applications. It
features a quad-core Arm Cortex-A55 and dual-core Arm Cortex-R52
configuration, with security features, and is designed for real-time
control and high-speed communication.

RZ/N2H SoC supports below features:
- Quad-core Arm Cortex-A55 and dual-core Arm Cortex-R52 configuration
- Security functions (optional)
- Encoder interfaces
  * 16 channels
  * EnDat 2.2, BiSS-C, A-format, and HIPERFACE DSL-compliant interfaces
  * Frequency-divided output from an encoder
- Various communications interfaces
  * Ethernet
    - EtherCAT slave Controller: 3 ports
    - Ethernet switch: 3 ports
    - Ethernet MAC: 1 port x 3 units
  *  USB 2.0 high-speed host/functions: 1 channel
  * CAN/CANFD (compliant with ISO11898-1): 2 channels
  * SCI with 16-byte transmission and reception FIFOs: 6 channels +
    12 channels (for encoder)
  * I2C bus interface: 3 channel for transfer at up to 400 kbps
  * SPI: 4 channels
  * xSPI: 2 channels
  * PCI Express Gen3: 2 lane x 1 port or 1 lane x 2 ports
  * SD card host interface: 2 channels
- Serial host interface
- 12 bits x 3 unit (4 channels for unit 0, 1, 15 channels for unit 2
- LCD Controller
- General-purpose I/O ports
- Trigonometric function unit
- 16-bit x 8 + 32-bit MTU3 (9 channels), 32-bit GPT (56 channels)
- 6-bit CMT (6 channels), 32-bit CMTW (2 channels)
