Subject: [PATCH 1/4] phy: qcom-qmp: Increase the phy init timeout

If we do full reset of the phy, it seems to take a couple of ms to come
up on my system so increase the timeout to 10ms.

This was found by full reset addition by commit 870b1279c7a0
("scsi: ufs-qcom: Add reset control support for host controller") and
fixes the regression to platforms by this commit.
