phy: msm: usb: Disable PHY IRQ during resume routine 



As a part of msm_otg_resume, USB reset happens which fires PHY
IRQ. This leads to various enumeration and SDP_CURRENT_MAX
notification issues on ADB cable connect, and low power mode
issue on cable disconnect.
Fix this by disabling PHY IRQ when msm_otg_resume starts and
until OTG comes out of LPM.
