Update the setDtimMultiplier aidl API documentation.

Browse Source 
Update the aidl API documentation to describe how setDtimMultiplier API
is supposed to work, i.e. we can call this API to set a maximum DTIM
multiplier value to use in driver, any larger value must not be accepted
and meanwhile it allows to set a specific multiplier by OEMs. Try to
make the description clear and avoid the ambiguity.

/**
* Set DTIM multiplier used when the system is in the suspended mode.
* Set maximum acceptable DTIM multiplier to hardware driver.
* Any multiplier larger than this maximum value must not be accepted since it will cause
* packet loss higher than what the system can accept, which will cause unexpected behavior
* for apps, and may interrupt the network connection.
*
* When STA is in the power saving mode and system is suspended,
* the wake up interval will be set to:
* 1) multiplier * DTIM period if multiplier > 0.
* 2) the driver default value if multiplier <= 0.
* Some implementations may apply an additional cap to wake up interval in the case of 1).
