sifive: fu540: Enable spi-nor flash support
HiFive Unleashed A00 support is25wp256 spi-nor flash,
So enable the same and add test result log for future
reference.
Tested on SiFive FU540 board.
Thanks to Sagar for various use cases and tests.
[QUAD mode in dt with spi-tx-bus-width: <4>]
pp opcode = 0x34 [QUAD MODE]
read opcode = 0x6c [QUAD MODE]
erase opcode = 0x21
SPI-NOR:
1. erase entire flash: Pass
2. write entire flash: Pass
3. read entire flash: Pass
4. cmp 32MiB read back data: Pass
5. MMC: Booted Linux and dtb from mmc
[SPI MODE in dt with spi-tx-bus-width: <1>]
pp opcode = 0x12 [SPI MODE]

2. write entire flash: Pass
3. read entire flash: Pass
