These patches add support for Loongson1B.

Changelog:

V6: Add USB support for Loongson1B.

V5: Add IS_ENABLED() macro for platform devices.

V4: Split the RTC patch, and merge the arch/mips parts into patch 2/4.
    Use 'KSEG1ADDR' instead of 'ioremap()' in registers definitions.

V3: Add RTC support for Loongson1B.

V2: Add Ethernet support for Loongson1B.

V1: Add basic support for Loongson1B.
