It's necessary to call spi_init() prior to calling spi_flash_probe()
such that the SPI drivers can do any work required prior to performing
SPI transactions. It could be argued that the drivers should handle
such situations, however the SPI API implementations seem to assume the
callers ensured spi_init() was called before any SPI transactions.
This fixes systems that failed to boot introduced by [1]. Issue tracked

2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY
The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not

Instead, provide a mechanism to retrieve an object that can

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.
