[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

The 'reg_1p8v' regulator is not used anywhere, so let's remove it.

From: Fabio Estevam <fabio.estevam@freescale.com>

According to the warp schematics there are no regulators for the USB OTG 
ports, so let's remove them.

[PATCH 3/3] ARM: dts: imx6sl-warp: Fix OTG roles

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

USBOTG1 always work on peripheral mode and USBOTG in host mode, so fix
their roles accordingly.

Tested by mounting the MMC card as a storage device:

modprobe g_mass_storage file=/dev/mmcblk0p2
