cros_bundle_firmware: update mmc flashing syntax
2013.01 upstream u-boot has a different mechanism for selecting boot
partition. Instead of specifying it in the "mmc read" or "mmc write"
command, it is specified during "mmc open". Wrap the read and write
commands with an "mmc open" / "mmc close" to select the boot
partition.
BUG=None
TEST=flashed on puppy with: "cros_bundle_firmware --board=puppy
--flash=mmc --write=usb
--dt=/build/puppy/firmware/dts/tegra114-dalmore.dts --servo=none"
