ASoC: omap-hdmi-audio: Force channel allocation only for OMAP4
There is a constraint in the OMAP4 HDMI IP that requires to use the 8-channel code when transmitting more than two channels. The constraint doesn't apply for OMAP5 so don't force the channel allocation in the sound driver as it can be done specifically for OMAP4 later in the hdmi4 core.
