ASoC: wm8737: Fixup setting VMID Impedance control register
According to the datasheet: R10 (0Ah) VMID Impedance Control BIT 3:2 VMIDSEL DEFAULT 00 DESCRIPTION: VMID impedance selection control 00: 75kΩ output 01: 300kΩ output 10: 2.5kΩ output WM8737_VMIDSEL_MASK is 0xC (VMIDSEL - [3:2]), so it needs to left shift WM8737_VMIDSEL_SHIFT bits for setting these bits.
