Adds support for some mixer controls to sun4i-codec: - Line-In - FM-In - Mic 2 - Capture Source - Differential Line-In

It also adds a mux for the capture source and the PGA for the MIC2 preamp.

Where possible, it uses SOC_DAPM_DOUBLE in order to cut down on the number of distinct controls in alsamixer.
