[Alison Wang] I verified QSPI boot on LS1021AQDS and LS1021ATWR boards based
on u-boot-spi/spi-nor branch. As we also support QSPI in SD boot, some modifications
are needed for ls1021aqds_sdcard_qspi_defconfig and ls1021atwr_sdcard_qspi_defconfig.
I submitted a set for the modifications, please help to review.

BTW, I have a concern about so much debugging information. Could we print them only when debugging?

drivers/mtd/spi-nor/m25p80.c:
printf("m25p80: 0x%p => cmd = { 0x%02x 0x%02x%02x%02x } chunk_len = %zu\n",
               buf, flash->command[0], flash->command[1], flash->command[2],
               flash->command[3], len);
