Subject: [PATCH 098/241] ARM: imx: ehci: fix host power mask bit

3.5.7.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Fritz <chf.fritz@...glemail.com>

commit 3d5e2abe6e265acc5e1fda810301243e9bac92b2 upstream.

This patch sets HPM (Host power mask bit) to bit 16 according to i.MX
Reference Manual. Falsely it was set to bit 8, but this controls pull-up
Impedance.
