The Primary-to-Sideband bus (P2SB) is used to access various peripherals
through memory-mapped I/O in a large chunk of PCI space. The space is
segmented into different channels and peripherals are accessed by
device-specific means within those channels. Devices should be added in
the device tree as subnodes of the p2sb.
This adds a uclass and enables it for sandbox.

Chromium EC commands can be up to 16-bits, so using a uint8_t here can
cause truncation. Update to use a uint instead.
It looks like this should likely have been done as a part of

for some reason.
