[RFC PATCH 15/37] cbus: retu: fix compile breakage on retu-headset

[felipe.balbi@xxxxxxxxx]

From: Felipe Balbi <felipe.balbi@xxxxxxxxx>

when building retu-headset as a  module, we need to
export retu_set_clear_reg_bits() and retu_read_adc().

While at that, also move the EXPORT_SYMBOL() macros
closer to the function definitions.
