Modify the corresponding vccio according to the schematic of
Sonoff iHost. This change aligns the device tree with the actual
hardware design and improves peripheral stability.

Reduce max-frequency from 50MHz to 25MHz to improve WiFi module stability
on some Sonoff iHost units. Remove unsupported or redundant properties,
and keep only minimal, validated configuration.

Sonoff iHost is gateway device designed to provide a Smart Home Hub,
it is based on Rockchip RV1126. There is also a version with 2GB RAM
based off the RV1109 dual core SoC.
Features:
- Rockchip RV1126
- 4GB DDR4
- 8GB eMMC
- microSD slot
- RMII Ethernet PHY
- 1x USB 2.0 Host
- 1x USB 2.0 OTG
- Realtek RTL8723DS WiFi/BT
- EFR32MG21 Silabs Zigbee radio
- Speaker/Microphone
This patch adds the initial device tree for this device, it is largely
based off the device trees for mainline Edgeble Neu2 and downstream
Rockchip rv1126-evb-v13 configs. It has been adapted with relevant
peripheral and GPIO pins for the iHost.
