[PATCH v4 1/2] dt-bindings: misc: qcom,fastrpc: Allow hex digits in compute-cb node names

[Ekansh Gupta <ekansh.gupta@oss.qualcomm.com>]

The patternProperties key for compute-cb subnodes used [0-9]* which
only matches decimal digits. However, per DTS convention, node unit
addresses must be the lowercase hexadecimal representation of the reg
value. For compute-cb nodes with reg values >= 10 (e.g. 12, 13, 14),
the correct node names are compute-cb@c, compute-cb@d, compute-cb@e
respectively, which are not matched by the current pattern.

Extend the pattern to [0-9a-f]+ to allow lowercase hex digits, making
it consistent with DTS unit address conventions. Also change * to +
to require at least one digit in the unit address.
