mfd: omap-usb-tll: Configure ULPIAUTOIDLE
The idle mode needs to be only disabled for UTMIAUTOIDLE while ULPIAUTOIDLE can be enabled. This matches the TLL_CHANNEL_CONF_i register configuration for ehci-tll in the Motorola Linux kernel tree for Wrigley 3G LTE modem on droid 4 and the modem still stays responsive.
