sunxi: Create helper function veryfing valid boot signature on MMC
This patch extracts checking for valid SD card "eGON.BT0" signature from
`board_mmc_init` into function `sunxi_mmc_has_egon_boot_signature`.
Buffer for mmc sector is allocated and freed at runtime. `panic` is
triggered on malloc failure.
