ASoC: msm: change default Dolby endpoint to EXT speakers

Android endpoint device is mapped to Dolby endpoint device and sent
to DAP post proc module in dsp. Dolby suggests the default device
should be external speakers when we can't find the mapping like in
case of combo devices in use.

ASoC: msm: Change the definition of port_session variable

The definition of the post session variable used during port
mixer command is 32 bit wide, if the port number selected
is more than 32 bit and set_bit will end up in changing the
variable other than port_session as it is out of bound access.
Change the port session variable to 64 bit to take care of out of bound
access.
