common: spl: spl_spi: add support for dynamic override of sf bus
Currently the SPI flash to load from is defined through the compile
time config CONFIG_SF_DEFAULT_BUS and CONFIG_SF_DEFAULT_CS, this
prevents the loading of binaries from different SPI flash using the
same build.E.g. supporting QSPI flash boot and OSPI flash boot
on J721E platform is not possible due to this limitation.
This commit adds lookup functions spl_spi_boot_bus()
and spl_spi_boot_cs for identifying the flash device based on the
selected boot device, when not overridden the lookup functions are
weakly defined in common/spl/spl_spi.c.
