Add cpu aliases to U-Boot specific dtsi for hifive-unleashed.
Without aliases we see that the CPU device sequence numbers are set
randomly and the cpu list/detail command will show it as follows:
=> cpu list
1: cpu@1 rv64imafdc
2: cpu@2 rv64imafdc
3: cpu@3 rv64imafdc
0: cpu@4 rv64imafdc
Seems like CPU probing with dm-model also relies on aliases as observed
in case spi. The fu540-c000-u-boot.dtsi has cpu nodes and so adding
corresponding aliases we can ensure that cpu devices are assigned
proper sequence as follows:
=> cpu list
1: cpu@1 rv64imafdc
2: cpu@2 rv64imafdc
3: cpu@3 rv64imafdc
4: cpu@4 rv64imafdc

Add a support for SPL which will boot from L2 LIM (0x0800_0000) and
then SPL will boot U-Boot FIT image (OpenSBI FW_DYNAMIC + u-boot.bin)
from MMC boot devices.
SPL related code is leveraged from FSBL
(https://github.com/sifive/freedom-u540-c000-bootloader.git)

Devicetree files in FU540 platform is synced from Linux, like other
platforms does. Apart from these U-Boot in FU540 would also require
some U-Boot specific node like clint.
So, create board specific -u-boot.dtsi files. This would help of
maintain U-Boot specific changes separately without touching Linux
dts(i) files which indeed easy for syncing from Linux between
releases.

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]
read opcode = 0xc [SPI 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

Add U-Boot specific dts file for hifive-unleashed-a00, this
would help to add u-boot specific properties and other node
changes without touching the base dts(i) files which are easy
to sync from Linux.
Added spi2 alias for qspi2 as an initial u-boot specific
property change.
spi probing in current dm model is very much rely on aliases
numbering. Even though the qspi2 can't come under any associated
spi nor flash it would require to specify the same to make proper
binding happen for other spi slaves.
