rockchip: add support for Theobroma Systems SOM-RK3588-Q7 Tiger module

The RK3588-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3588.

It provides the following feature set:
 * up to 16GB LPDDR4x
 * on-module eMMC
 * SD card (on a baseboard) via edge connector
 * Gigabit Ethernet with on-module GbE PHY
 * HDMI/eDP
 * MIPI-DSI
 * 4x MIPI-CSI (3x on FPC connectors, 1x over Q7)
 * HDMI input over FPC connector
 * CAN
 * USB
   - 1x USB 3.0 dual-role (direct connection)
   - 2x USB 3.0 host + 1x USB 2.0 host
 * PCIe
   - 1x PCIe 2.1 Gen3, 4 lanes
   - 2xSATA / 2x PCIe 2.1 Gen1, 2 lanes
 * on-module ATtiny816 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
 * on-module Secure Element with Global Platform 2.2.1 compliant
   JavaCard environment

The support is added for Tiger on Haikou devkit, similarly to RK3399
Puma and PX30 Ringneck.
