Update the cache settings for the Aries m100pfsevp board. This
assigns scratchpad ways for this board as well, as seen in the
commit 491ae6c.

The source directory contents of the OpenSBI directory lib/sbi may be
listed with a one-line wildcard. This makes the Make.defs file look
simpler. The rest of the files need to be picked one at a time.

OpenSBI may be compiled as an external library. OpenSBI commit d249d65
(Dec. 11, 2021) needs to be reverted as it causes memcpy / memcmp to
end up in the wrong section. That issue has yet no known workaround.
OpenSBI may be lauched from the hart0 (e51). It will start the U-Boot
and eventually the Linux kernel on harts 1-4.
OpenSBI, once initialized properly, will trap and handle illegal
instructions (for example, CSR time) and unaligned address accesses
among other things.
Due to size size limitations for the mpfs eNVM area where the NuttX
is located, we actually set up the OpenSBI on its own section which
is in the bottom of the DDR memory. Special care must be taken so that
the kernel doesn't override the OpenSBI. For example, the Linux device
tree may reserve some space from the beginning:
opensbi_reserved: opensbi@80000000 {
reg = <0x80000000 0x200000>;
label = "opensbi-reserved";
};
The resulting nuttx.bin file is very large, but objcopy is used to
create the final binary images for the regions (eNVM and DDR) using
the nuttx elf file.

Assign ways to L2 zerodevice. L2 zero device is used for
the scratchpad functionality. The area may be used for the
harts communicating to each other.

- "op_mode" instead of "mode" (compilation error)
- CONFIG_ISL29023_I2C_FREQUENCY instead of CONFIG_LM75_I2C_FREQUENCY
(probably a leftover)
- Fix a couple of format warnings: now using PRIu32
- Also minor comment changes
For FAT the same buffer is used for read and writes, there
is a possibility a cache line is dirty. But the fs is
not dirty and will not write the sector to disk. This can
be seen https://github.com/PX4/NuttX/pull/175
When the system is busy that cache line can be evicted after the
RX DMA has completed and overwrite the data in memory. The solution
is to invalidate before the DMA to prevent an evection causing an
overwite, and after the DMA it to insure coherency.
This pull request improves the dependencies for Makefile.unix::context rule.
* `include/math.h`, `include/float.h`, `include/stdarg.h`, `include/setjmp.h` are only added to `context`'s dependency if the Kconfig value is set. This prevents `context` from trying to make `include/math.h` only to find out there's no command to create the file.
* Instead of executing $(CONTEXTDIRS) in a for loop in the `context` rule, $(CONTEXTDIRS) are added as a dependency to `context` and a rule is created to create the targets. Real files are used, to prevent needlessly rebuilding the same `context` over and over and over again.
* Instead of making the directory `staging`, add it as an order-only dependency for `context`. this ensures the directory is only created if it doesn't exist.

According to Make documentation:
- "Commas and unmatched parentheses or braces cannot appear in the text
of an argument as written";
- "Leading spaces cannot appear in the text of the first argument as
written".
Although in the current state it was not resulting in parsing issues, it
is better to fix it.
