From: Bagas Sanjaya <bagasdotme@gmail.com>

Add classes:
* Core subsystems
* Storage
* Networking
* Peripherals and devices
* Embedded systems
* Integrity
* Virtualization
* Miscellaneous

There is a FIXME that says to organize subsystems listed in
subsystem-apis.rst. Fulfill it by categorize remaining subsytems
by purpose/themes, while sorting entries in each category.

HID devices are already categorized in 3c591cc954d56e ("docs:
consolidate human interface subsystems").

Changes:
v3: add Integrity, Virtualization and Miscellaneous per Bagas Sanjaya
v2: add Core subsystems, Networking, Peripherals and Embedded
v1: add Storgre category
