This series of patches:
        - Add OpenTitan lifecycle controller with basic functionality
        - Connects it to OpenTitan

Currently in OpenTitan, we skip the `boot_rom` since is has become more
complex and we do not have all the support in QEMU to use it. One of the
missing pieces to getting the `boot_rom` working is the lifecycle
controller. There's a particular `magic_value` that is kept in the
`LC_STATE` register which is checked by the `boot_rom`.

With this basic implementation of the device, we can get past the
lifecycle controller in the `boot_rom` check stage. Testing was done
using TockOS (running QEMU with `-d in_asm`) to see how far in the boot
rom we get.

End goal is to add support to all device models in QEMU that are
required by the OpenTitan `boot_rom` such that we can use it as the
`bios`.
