Consider the association between modem[1] and DCXO, this patch is a fix for
eb5e47d("mediatek/mt8183: update dcxo output buffer setting") [2]
We should not disable XO_CEL and block the bblpm request when modem is still ON.
For power-saving, we still could disable unused XO_CEL and
mask request to disable unused power mode when modem is no longer be used.
