omap4: Fix ULPI PHY init for ES1.0 SDP
omap4: Fix ULPI PHY init for ES1.0 SDP

Commit 6aa85a5ae610106d89e50c7e1f760c56d12f9bc4 (omap4: 4430sdp:
enable the ehci port on 4430SDP) added code to enable EHCI
support on 4430sdp board.

Looks like the ULPI pin does not seem to be muxed properly on ES1.0
SDP and this causes the system to reboot when the ULPI PHY is
enabled.

Fix this by muxing the pin, this is the same setting for
both ES1.0 and ES2.0. Also add checking for gpio_request.
