SMIF interface for baseboard flash

The kit is provisioned with an optional QSPI SMIF-based flash in the baseboard. To isolate the default flash
available in the M.2 board and use the optional baseboard flash, a rework is needed in the kit. The SMIF
memory interface I/Os are shared between the SMIF QSPI flash of the baseboard and the M.2 board flash.
To perform the necessary rework on the board by removing or adding the corresponding 0 Ω resistors to work
with baseboard SMIF memory modules. See
