These patches support single-core DTS boot to the serial port login
interface, which can be operated using conventional commands.
I have successfully tested it on the Loongson 2K1000 machine.
pmon: http://cgit.loongnix.org/cgit/pmon-loongson3/
Note:
After the basic support is merged,
I will commit SMP and other driver support in the future.

Add IO interrupt controller support for Loongson-2K1000, different
from the Loongson-3A series is that Loongson-2K1000 has 64 interrupt
sources, 0-31 correspond to the device tree liointc0 device node, and
the other correspond to liointc1 node.
