[PATCH v3 1/2] dt-bindings: sifive: add cache-set value of 2048

[Conor Dooley]

From: Atul Khare <atulkhare@xxxxxxxxxxxx>

Fixes Running device tree schema validation error messages like
'... cache-sets:0:0: 1024 was expected'.

The existing bindings had a single enumerated value of 1024, which
trips up the dt-schema checks. The ISA permits any arbitrary power
of two for the cache-sets value, but we decided to add the single
additional value of 2048 because we couldn't spot an obvious way
to express the constraint in the schema.
