regulator: max8649 - fix setting extclk_freq

AxelLin · Liam Girdwood · commit 0f69c897f378 · 2010-10-02T14:19:45.000+01:00
The SYNC bits are BIT6 and BIT7 of MAX8649_SYNC register.
pdata-&gt;extclk_freq could be [0|1|2].
(MAX8649_EXTCLK_26MHZ|MAX8649_EXTCLK_13MHZ|MAX8649_EXTCLK_19MHZ)
It requires to left shift 6 bits to properly set extclk_freq.
