mfd: omap-usb-host: Fix improper mask use.
commit 46de8ff8e80a6546aa3d2fdf58c6776666301a0c upstream.
single-ulpi-bypass is a flag used for older OMAP3 silicon.
The flag when set, can excite code that improperly uses the
OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit.
Instead it clears all of the other bits disabling all of the ports in
the process.
