dt-bindings: mmc: loongson,ls2k0500-mmc: Add compatible for Loongson-2K0300

Add "loongson,ls2k0300-mmc" dedicated compatible to represent the
eMMC/SD/SDIO controller interface of the Loongson-2K0300 chip.

Its hardware design is similar to that of the Loongson-2K2000, but it
suffers from hardware defects such as missing CMD48 interrupts.
