[PATCH] ASoC: wm_hubs: Fix DC Servo readback

[Nikesh Oswal]

wm_hubs is a common driver code shared by WM8958, WM1811, WM8944
and WM8993 all these codecs have the DC Servo Values either in register
57h or 59h. Current code was reading register 58h for WM8958 and WM8994
revisions 2 and 3 but looking at the data sheet the DC Servo Values are
stored in register 57h for these codecs. This patch fixes it by reading
the correct register for DC Servo
