ARM: dts: msm: Configure spkdrv supply for APQ8084 



The APQ8084 CDP and MTP has Codec speaker driver which requires power
supply. Configure speaker driver supply as an on demand so that codec
driver can turn it on only when it's required.
Liquid has external supply which should be controlled by its ASoC machine
driver. Configure Liquid's speaker driver supply with 0V and 0Amp to make
codec driver doesn't complain about lack of spkdrv supply.
