Subject: [PATCH v2 2/7] regulator: mt6358: Sync VCN33_* enable status after checking ID

Syncing VCN33_* enable status should be done after checking the PMIC's
ID, to avoid setting random bits on other PMICs.

Suggested-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>
Fixes: 65bae54e08c1 ("regulator: mt6358: Merge VCN33_* regulators")
Signed-off-by: Chen-Yu Tsai <wenst@...omium.org>
