Currently, the code assumes the nCS pin of spi nor flash is connected to
either nRESET(pin 15) or nTRST(pin 3). But it is incompatible with the
pinout from official JFlash SPI, whereas the nCS pin is wired to TMS(pin
7).
This commit adds cs=tms option to share the same pinout as JFlash SPI.
It works by toggling TMS in assert_cs and deassert_cs, and sets TMS to
zero in jlink_spi_send_command. The default option is set to cs=reset
for backward compatibility.
Tested on macOS 13.3.1 with JLink and Winbond W25Q128

This adds a parameter to drive the aux pin low (or high if you
explicitly want the previous behavior). Some boards need to have a reset
pin driven low before the firmware can be safely flashed. With the Bus
Pirate, this is most easily done with the auxiliary pin.

Use sphinx (sphinx-doc.org) to generate the UNIX man page from an
reStructuredText file instead of dealing with plain groff.
Use `meson setup -Dman-pages=enabled` to build the man page, and
`meson setup -Ddocumentation=enabled` to build the web documentation
explicitly. Both are enabled automatically if sphinx-build is found.
The man page will be installed as `<meson_mandir>/man8/flashrom.8` and
The html documentation in <meson_datadir>/doc/flashrom/html`.
The Makefile builds only the man-page format.
Increase the minimum version of meson from 0.53.0 to 0.57.0 to be
able to pass environment variables to the custom_target() command. That
is needed to pass the FLASHROM_VERSION to the documentation.
