MIPS: Loongson 1B: Add board support
Adds basic platform devices for Loongson 1B, including serial port, ethernet, USB, RTC and interrupt handler. The Loongson 1B UART is compatible with NS16550A, the Loongson 1B GMAC is built around a Synopsys IP Core. Use normal instead of enhanced descriptors. Thanks to Giuseppe for updating the normal descriptor in stmmac driver. Thanks to Zhao Zhang for implementing the RTC driver.
