Subject: [PATCH 4.19 31/55] phy: qcom-qmp: Increase PHY ready timeout

From: Bjorn Andersson <bjorn.andersson@...aro.org>

[ Upstream commit cd217ee6867d285ceecd610fa1006975d5c683fa ]

It's typical for the QHP PHY to take slightly above 1ms to initialize,
so increase the timeout of the PHY ready check to 10ms - as already done
in the downstream PCIe driver.
