bios/boot: make SDCard boot more flexible using a boot.json file on the SDCard.

The BIOS now reads the boot.json file to know which files need to be copied to RAM and where.
It will fallback to boot.bin is no boot.json is found and boot will fail if neither is found.

Example of boot.json file used to boot Linux-On-LiteX-Vexriscv:
{
"Image":        "0x40000000",
"rootfs.cpio":  "0x40800000",
"rv32.dtb":     "0x41000000",
"emulator.bin": "0x41100000"
}
