I am wanting to use a Raspberry Pi 3 to communicate with two Texas Instruments CC2538s (over serial USB), I am wondering if the RP will be able to provide enough power over its USB ports to power these.

From what I can tell the CC2538s require 3.3V to power them via the SmartRF06EB board.

Will the RP be capable of this or will it not work for what I need to do

The short answer is that the Raspberry Pi can provide just over 1 amp (1.2-1.5 or so for all the USB ports combined. It is at 5 volts.

You said you need 3.3 volts - there are modules that can step the 5 Volts down to 3.3

See this table that shows the output limitations of the various models:
