ASoC: cs42l51: Constify struct i2c_device_id

Browse Source 
'struct i2c_device_id' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security.

While at it, also add some space to be consistent with cs42l51_of_match a
few lines below.

On a x86_64, with allmodconfig:
Before:
