bit 0 of HPROUT_CTRL and HPRCOM_CTRL is handled by DAPM:
"Right HP Out"
"Right HP Com"

and this will modify the HPR and HPRCOM (right channels) only.
You should add two controls:
/* HP/HPCOM volumes. From 0 to 9 dB in 1 dB steps */
static DECLARE_TLV_DB_SCALE(hp_tlv, 0, 100, 0);
SOC_DOUBLE_R_TLV("HP Playback Volume", HPLOUT_CTRL, HPROUT_CTRL, 4, 9,
0, hp_tlv);
SOC_DOUBLE_R_TLV("HPCOM Playback Volume", HPLCOM_CTRL, HPRCOM_CTRL, 4,
9, 0, hp_tlv);
