hw/nvram: Introduce Xilinx Versal eFuse device
This implements the Xilinx Versal eFuse, an one-time
field-programmable non-volatile storage device. There is
only one such device in the Xilinx Versal product family.
This device has two separate mmio interfaces, a controller
and a flatten readback.
The controller provides interfaces for field-programming,
configuration, control, and status.
The flatten readback is a cache to provide a byte-accessible
read-only interface to efficiently read efuse array.
