asoc: fix possible overflow issue for routing driver
The reg in soc_mixer_control is 32-bit. When using SOC_SINGLE_EXT, the value of FE DAI ID which is passed as shift(to be operated on the reg) may be more than 31, which may cause overflow. Use SOC_DOUBLE_EXT instead of SOC_SINGLE_EXT so that the reg field can be set to SOC_NO_PM to avoid any DAPM operation, while passing BE and FE IDs in shift and rshift fields. And these values can be retrieve in get/put functions and use them. This is to avoid any possible overflow in DAPM operation.
