Loongson64g is Loongson 3A4000, whose UART controller is compatible with Loongson 2K1500, which is NS16550A-compatible with an additional fractional frequency divisor register. Update the compatible strings to reflect this, so that 3A4000 can benefit from the fractional frequency divisor provided by loongson-uart. This is required on some devices, otherwise their UART can't work at some high baud rates, e.g., 115200. Tested on Loongson-LS3A4000-7A1000-NUC-SE with a 25MHz UART clock. Without fractional frequency divisor, the actual baud rate was 111607 (25MHz / 16 / 14, measured value: 111545) and some USB-to-UART converters couldn't work with it at all. With fractional frequency divisor, the measured baud rate becomes 115207, which is quite accurate.
