[PATCH] regulator: Fix WM8994 LDO enable gpio set when probed

[Joonyoung Shim <jy0922.shim@samsung.com>]

The enable time needs to enable WM8994 LDO, but WM8994 LDO is enabled
without the enable time at the probe function. This can cause the
problem to try i2c operation before LDO is enabled.

This patch sets to 0 WM8994 LDO enable gpio when probed then if it is
requested to enable WM8994 LDO, will be enabled by enable interface of
regulator core with enable time.
