[PATCH v3 1/2] regulator: qcom-rpmh-regulator: fix regulator mode mismatch

[Federico Amedeo Izzo via B4 Relay]

From: Federico Amedeo Izzo <federico at izzo.pro>

Fix issue where regulator mode could not be set to the
"regulator-initial-mode" value from dts.

priv->mode was initialized to "regulator-initial-mode", but this could
differ from the actual regulator mode.
In this case rpmh_regulator_vrm_set_mode() would return early, thinking
that the mode is already correct.

Setting an invalid mode on probe solves the issue.
