soc/amd/common/block/lpc: Add custom SPI DMA boot device
This is a copy of mmap_boot.c and mem_rdev_ro_ops. I split it up so it
was easier to review.
The next patches will add support for the SPI DMA controller. This will
provide a minor speed up vs using mmap reads. It will also provide the
facilities to perform asynchronous SPI loading.
BUG=b:179699789
TEST=Boot guybrush to OS
