This commit brings 3 fixes/improvements applied to the Kconfig options
for SPI Flash file system support on board bring-up:
- (925e8f9) Optionally mount SPI Flash MTD on bring-up
- (f74c6f7) Transform SPI Flash FS deps into reverse deps
- (9056cab) Select MTD_SMART if SmartFS is selected for SPI Flash MTD

Currently, when no file system is selected, the "choice" lists zero
entries, which is very confusing to the user. To handle this, the
"choice" options have their dependencies ("depends on") transformed into
reverse dependencies ("select").

Give the user the option to simply register the SPI Flash MTD as a
device node on /dev.
Currently, this is achievable only when SmartFS (which is the default FS
option) is disabled by force. This behavior is fixed by using the
"optional" Kconfig keyword, which makes the "choice" selectable.

This adds DDR training. The training has a small chance of failing,
and then the training is restarted.
DDR training cannot be done meaningfully while the software is
in DDR. If the system is intended to run from eNVM, like a
bootloader, the linker script should be tuned to utilize the envm
region as follows:
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
256 bytes are reserved for the system; The fixed block may be
installed from the 'hart-software-services' -repository:
https://github.com/polarfire-soc/hart-software-services.git
For example, the 256-byte image: hss-envm-wrapper-bm1-dummySbic.bin
may be prepended on the nuttx bootloader image in the following
manner:
cat hss-envm-wrapper-bm1-dummySbic.bin > nuttx_bootloader.bin
cat nuttx.bin >> nuttx_bootloader.bin
riscv64-unknown-elf-objcopy -I binary -O ihex --change-section-lma
*+0x20220000 nuttx_bootloader.bin flashable_image.hex
This provides an image 'flashable_image.hex' that may be flashed on
the eNVM region via Microsemi Libero tool.

Since the tests were removed from the drivers, there is no need for
these defconfigs anymore.

-march=rv64gc -mabi=lp64 does not resolve lib paths for
riscv64-unknown-elf-gcc resulting in lib not found errors.
Changing it to -march=rv64imafc -mabi=lp64f that is the default
used in Sipeed repositories.
