dra7xx_evm: Add QSPI_4 support, qspiboot build target
We previously only supported QSPI_1 (single) support. Add QSPI_4 (quad) read support as well. This means we can be given one of two boot device values, but don't care which it is, so perform a fixup on the QSPI_4 value. We add a qspiboot build target to better show how you would use QSPI as a boot device in deployment. When we boot from QSPI, we can check the environment for 'boot_os' to control Falcon Mode.
