Fix several typos and improve comment clarity in the CXL device types
docs:
 "w/" replaced with "with"
 "sill" -> "still"
 "The allows" -> "This allows"
 "capacity" corrected to "capable"
 "more devices" corrected to "more hosts" in MLD description

These changes improve readability and enhance the documentation quality.

This is subtly incorrect.

A *Multi-Headed* MLD presents one or more devices to one or more hosts.

A *Multi-logical Device* presents one or more devices to one or more
upstream devices (such as a switch).

You can have a Single-Headed Multi-Logical Device that presents 2
"Logical Devices" to a single upstream device (host or switch).

So please change "one or more hosts" to "one or more upstream devices".


With that change you may add

I fixed it up with your suggestion and applied to cxl/next. Please check and make sure the fix is correct. Thanks!
