Subject: [PATCH 06/10] ARM: davinci: da850-evm: call regulator_has_full_constraints()

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

[ Upstream commit 0c0c9b5753cd04601b17de09da1ed2885a3b42fe ]

The BB expander at 0x21 i2c bus 1 fails to probe on da850-evm because
the board doesn't set has_full_constraints to true in the regulator
API.

Call regulator_has_full_constraints() at the end of board registration
just like we do in da850-lcdk and da830-evm.
