Subject: [PATCH] regulator: lp873x: Update the enable mask for LDOs and BUCKs
The reset value of the EN_PIN_CTRL bit fields of LDOs and BUCKs
need not be set correctly. Hence update the enable mask to include
the EN_PIN_CTRL bit. While enabling this should be set to 1 so
that all the regulators are tied to EN pin.
