media: imx7-mipi-csis: Add a check for devm_regulator_get

Browse source

devm_regulator_get may return an error but mipi_csis_phy_init misses
a check for it.
This may lead to problems when regulator_set_voltage uses the unchecked
pointer.
This patch adds a check for devm_regulator_get to avoid potential risk.
