ASoC: fsl_asrc: spba clock is needed by asrc device
ASRC need to enable the spba clock, when sdma is using share peripheral
script. In this case, there is two spba master port is used, if don't
enable the clock, the spba bus will have arbitration issue, which may
cause read/write wrong data from/to ASRC registers
