arch: mips: Update initrd_start and initrd_end
Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which represents the start of kseg0 and represents a virtual address. Meaning that the initrd_start and initrd_end point somewhere kseg0. When these parameters are passed to linux kernel through DT they are pointing somewhere in kseg0 which is a virtual address but linux kernel expects the addresses to be physical addresses(in kuseg) because it is converting the physical address to a virtual one. Therefore update the uboot to pass the physical address of initrd_start and initrd_end by converting them using the function virt_to_phys before setting up the DT.
