ASoC: Intel: sof_es8336: remove hard-coded SSP selection
For some reason we open-coded the SSP selection and only supported
SSP0, 1 and 2. On ApolloLake platforms, the SSP5 can be used as well
for the ES8336 hardware link.
Remove hard-coded if/else code and align with same code already used
in the SOF driver.
