drivers/spi: provide optional implementation of boot_device_rw()
On many x86 platforms the boot device is SPI which is memory
mapped. However, in order to write to the boot device one needs
to use the SPI api. Therefore, provide a common implementation
of boot_device_rw() which has no mmap() functionality. It only
reads, writes, and erases. This will be used in the existing
infrastructure but in a SPI agnostic way.
Two options are added:
1. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP
2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY
The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not
selected. The latter can be used to include the implementation
in the early stages such as bootblock, verstage, and romstage.
