risv: dts: microchip: add mmc0 and mmc1 aliases on BeagleV Fire

The BeagleV Fire features an eMMC connected to the SD/MMC controller in
the MSS, along with a microSD slot using the SPI interface. This patch
creates aliases in the BeagleV Fire device tree, assigning mmc0 to the
eMMC and mmc1 to the microSD interface
