  In some rare cases, buses will not have *any* bus-scaling clocks,
which is "fine", as the voting can be done through RPM provided that
the necessary QoS clocks are enabled. Allow specifying a negative (-1)
number of clocks to make the driver accept such cases, without having
to add a lot of boilerplate to all existing ICC drivers for SoCs with
SMD RPM.

FWIW this value was previously being assigned to a >>signed<< integer
as well.
