soc/amd/common/block/spi: remove code duplication

This removes all the duplicated code and logic and leverages
the existing ones in libraries themselves. The current side
effect is that protection cannot be fully enabled because the
read, write, and write enable command are not exposed in struct
spi_flash currently. That support can be revised if protection
scheme makes sense for our use-cases once it's better understood.
