Confirmed with milkv, only the sd card version is sold
by default for duo in the market. The spi pins are
provided through stamp holes, so that users can solder
the corresponding components on their baseboard during
secondary development.
In order to simplify maintenance work, the mainline
will only support the sd-card version and no longer
support spinor/spinand.
Updated config files the same in this patch.

After first called from uart open, the dw8250_uart_configure
API cannot be called again. Otherwise, this will mess up the
device, and uart will not act properly to interrupt again.
Analysis: Configure uart device will close recive interrupte,
causing uart device to malfunction.
Solution: After configure uart device, enable the device's
recive interrupte.

Supports both big and little cores of RISC-V C906,
but does not support ARM cores. Currently, only UART
drivers are supported on the peripherals.
