From: Marc Gonzalez <marc.w.gonzalez@xxxxxxx> [ Upstream commit 5206026404190125436f81088eb3667076e56083 ] readl_poll_timeout() calls usleep_range() to sleep between reads. usleep_range() doesn't work efficiently for tiny values. Raise the polling delay in qcom_qmp_phy_enable() to bring it in line with the delay in qcom_qmp_phy_com_init().
