[spi_device/dv] Update scb to check upload related CSRs

Scb updates:
1. Added checker for upload interrupt and upload status CSRs
2. Consolidated 2 types of queue for upload cmd/addr
3. Aligned with design change #14640 that last_read_addr is only updated in
flash mode

Minor sequence updates
1. Use a separate thread to read upload data and clear busy bit. Another
thread to drive SPI command and wait for busy to clear
2. Skip reading upload status unless there is an upload interrupt, so that scb
doesn't need to model upload status cycle accurately
