Get the clocks supplied by Platform(Board) to NXP Layerscape SOC IPs

@param[in] ClockType Variable of Type NXP_IP_CLOCK. Indicates which IP clock

is to be retrieved.

@param[in] ... Variable argument list which is parsed based on
|
ClockType. e.g. if the ClockType is NXP_I2C_CLOCK, then

the second argument will be interpreted as controller

number.

if ClockType is NXP_CORE_CLOCK, then second argument

is interpreted as cluster number and third argument is
|
interpreted as core number (within the cluster)
|
|
@return Actual Clock Frequency. Return value 0 should be

interpreted as clock not being provided to IP.
