Combined DCD MUSB implementations

Combined the new MAX32 MUSB implementation with the existing (TI) implementation to provide generic code base for working the MUSB DCD peripheral.
 - Added abstraction calls for FIFO setup, EP registers, Ctrl registers and interrupt setup.
 - Combined TM4C and MSP432E into a single header file.
 - Created musb_max32.h, and removed the MAX32 specific C implementation.
 - Updated MAX32 build system to use dcd_musb.c.
 - Added MAX32 conditions for cdc_dual_ports example descriptors missed during first testing.
