Subject: [PATCH] regulator: qcom-rpmh: Fix pm8010 pmic5_pldo502ln minimum voltage

The relevant documents and the dtsi specify the minimum value at 1.808v not
1.8v.

Prior to this fix we get the following error on boot:
[    1.353540] vrej_l3m_1p8: failed to get the current voltage: -ENOTRECOVERABLE
[    1.353544] qcom-rpmh-regulator 17500000.rsc:regulators-9: ldo3: devm_regulator_register() failed, ret=-131
[    1.353546] qcom-rpmh-regulator: probe of 17500000.rsc:regulators-9 failed with error -131

Fixes: 2544631faa7f ("regulator: qcom-rpmh: add support for pm8010 regulators")
