Add 1,35ghz opp register / clock: remove waiting command:

Some clocks are enabled by programming the MODULEMODE bit field of the PRCM
CLKCTRL registers. For these clocks, we should wait for the module to
transition from the idle state when we enable them. For other clocks, such as
optional clocks, that are enabled via other bits in the CLKCTRL registers, the
idle state is not updated when we enable them and so we should not wait for
the idle state to change when we enable them. This is causing unnecessary
delays to occur when enabling optional clocks as we are waiting for the idle
state to change and eventually timeout.
