/**
Return the input clock frequency to an IP Module.
This function reads the RCW bits and calculates the PLL multiplier/divider
values to be applied to various IP modules.
If a module is disabled or doesn't exist on platform, then return zero.
@param[in] BaseClock Base clock to which PLL multiplier/divider values is
to be applied.
@param[in] ClockType Variable of Type NXP_IP_CLOCK. Indicates which IP clock
is to be retrieved.
@param[in] Args 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. e.g. if there are four i2c controllers in SOC,
then this value can be 0, 1, 2, 3
e.g. 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.
