ASoC: es8316: fix register sync error in suspend/resume tests 



The SOF CI tests report failures with the following error thrown

kernel: es8316 i2c-ESSX8336:00: Unable to sync registers 0x0-0x1. -121

ES8336 only supports I2C read/write one byte a time, so we do need to
set the .use_single_read and .use_single_write flags to avoid this
sync issue.
