Sergiu Cuciurean 20be66c193 iio: dac: ti-dac7612: Replace indio_dev->mlock with own device lock 
As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock on the device's state from potential concurrent write
accesses from userspace. The write operation requires an SPI write, then
toggling of a GPIO, so the lock aims to protect the sanity of the entire
sequence of operation.

This is part of a bigger cleanup.
