Fabio Estevam 0247a7bcd4 USB: ehci-mxc: Setup portsc register prior to accessing OTG viewport
In order to read/write to the i.MX OTG viewport register it is necessary to setup
the PORTSCx register first.

By default i.MX OTG port is configured for USB serial PHY. In order to use a ULPI PHY
the PORTSCx register needs to be configured properly.

commit 724c852 (USB: ehci/mxc: compile fix) placed the PORTSC setup after the OTG
viewport is accessed and this causes ULPI read/write to fail.

Revert the PORTSC setup order.

Tested on a MX31PDK board with a ISP1504 transceiver:

ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
mxc-ehci mxc-ehci.0: initializing i.MX USB Controller
ULPI transceiver vendor/product ID 0x04cc/0x1504
Found NXP ISP1504 ULPI transceiver.
ULPI integrity check: passed.
