SG2002 chip, the B(ase) version is deprived of Wifi/Bluetooth and Ethernet.
Add only support for UART and SDHCI.

Have you test you patch with a real board? Especially
for device "uart1" and "i2c0", I suspect your

Hi, Thomas Bonnefille,
Can you please double check and feedback, I want to confirm this before
acking this change.
As you know, rc6 will come next week and I'm planning a pr next week.

Chen
