The target ID of the base hub is currently set to KIP (keyboard/
peripherals). However, even though it manages such devices with the KIP
target ID, the base hub itself is actually accessed via the SAM target
ID. So set it accordingly.
Note that the target ID of the hub can be chosen arbitrarily and does
not directly correspond to any physical or virtual component of the EC.
This change is only a code improvement intended for consistency and
clarity, it does not fix an actual bug.

Similar to the target category (TC), the target ID (TID) can be one
value out of a small number of choices, given in enum ssam_ssh_tid.
In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text
expansion to, both, remove some textual clutter for the target category
values and enforce that the value belongs to the known set. Now that we
know the names for the target IDs, use the same trick for them as well.
Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

Instead of hard-coding the target ID, use the respective enum
ssam_ssh_tid value.

Split out subsystem device hub drivers into their own module. This
allows us to load the hub drivers separately from the registry, which
will help future DT/OF support.
While doing so, also remove a small bit of code duplication.
