usb: dwc3: core: Call dwc3_core_get_phy() before initializing phys
commit f54edb539c
("usb: dwc3: core: initialize ULPI before trying to
get the PHY") moved call to dwc3_core_get_phy() from dwc3_probe() to
dwc3_core_init() after dwc3_core_soft_reset(). But
dwc3_core_soft_reset() calls phy_init(), therefore dwc3_core_get_phy()
needs to be called before dwc3_core_soft_reset().
Fix this by moving call to dwc3_core_get_phy() before
dwc3_core_soft_reset().
This fixes the following abort seen on DRA7xx platforms
[ 24.769118] usb usb2: SerialNumber: xhci-hcd.1.auto
[ 24.781144] hub 2-0:1.0: USB hub found
[ 24.787836] hub 2-0:1.0: 1 port detected
[ 24.809939] Unhandled fault: imprecise external abort (0x1406) at 0x00000000
