Documentation: x86: Remove cdpl2 unspported statement and fix capitalisation

"L2 cache does not support code and data prioritization". This isn't
true, elsewhere the document says it can be enabled with the cdpl2

When CDP is enabled L3 control is split into two separate resources
so you can specify independent masks for code and data like this::
L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
L3DATA:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
L3CODE:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
L2 schemata file details

L2 cache does not support code and data prioritization, so the
schemata format is always::
CDP is supported at L2 using the 'cdpl2' mount option. The schemata
format is either::

or
L2DATA:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
