ASoC: mt6358: Remove undefined HPx Mux enumeration values

The HPx Mux enumerations define values 5, 6 and 7 but describe them as
"undefined" and map them to the value 0 on writing. Given the descriptions
and behaviour it seems that these values are invalid and should not be
present in the register, the current behaviour is detected as problematic
by mixer-test:

# # HPL Mux.0 expected 5 but read 0, is_volatile 0
# # HPL Mux.0 expected 6 but read 0, is_volatile 0
# # HPL Mux.0 expected 7 but read 0, is_volatile 0

Remove the values from the enumeration, this will prevent userspace setting
them.
