[PATCH] spi: docs: adjust summary to CONFIG_SYSFS_DEPRECATED removal

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

With commit 721da5cee9d4 ("driver core: remove CONFIG_SYSFS_DEPRECATED and
CONFIG_SYSFS_DEPRECATED_V2"), ./scripts/checkkconfigsymbols.py indicated
an unresolved reference to the config SYSFS_DEPRECATED in the SPI summary
documentation.

Simply, delete the sentence referring to the removed config there. Also
update the documentation, as these sys/class entries should always be
symlinks, as the commit message of the commit above suggests.

Mark, Greg, Jens, please confirm that these sys/class entries now always
are symlinks. That is simply my guess after reading a bit on sysfs_deprecated
also changed compared to the normal setup, but I am not the expert here.

 How does board-specific init code declare SPI devices?
