lib/boot_device: add RW boot device construct
The current boot device usage assumes read-only semantics to
the boot device. Any time someone wants to write to the
boot device a device-specific API is invoked such as SPI flash.
Instead, provide a mechanism to retrieve an object that can
be used to perform writes to the boot device. On systems where
the implementations are symmetric these devices can be treated
one-in-the-same. However, for x86 systems with memory mapped SPI
the read-only boot device provides different operations.
