ASoC: cs35l32: Use case range at appropriate places
Use case range syntax makes the code shorter with better readability when
we have a large number of continuous switch cases.
Below are the summary of readable/volatile/precious registers.
The readable registers:
0x01 ~ 0x0D, 0x0F ~ 0x1C
The volatile registers:
0x01 ~ 0x05, 0x15 ~ 0x18
The precious registers:
0x15 ~ 0x18
No functional change with this patch.
