This patch fixes two bugs of OUT transfer in double buffer case:
-USE_MODE1 should be enabled except for ANOMALY_05000456 case, or
else may cause infinite hang and data error bug in double buffer

This patch fixes one bugs of OUT transfer in double buffer case:
-the current code only enable autoclear for dma mode 1, and not
for dma mode 0
Without this patch, test #5 of usbtest can't be passed if we
configure musb as g_zero and use fifo mode 3 to enable double
buffer mode.
From: Ming Lei
DMA length should not go beyond the availabe space of request buffer,
so fix it.

This patch set fixes two kinds of musb-gadget bug:

now we can use musb double buffer

Panda uses both twl6030 otg phy(vbus, id) and internal
phy(data lines, DP/DM), so removes usb_nop_xceiv_register to make
twl6030 otg driver working since current otg code only supports
one global transceiver. Otherwise, musb doesn't work without
the remove.

No mattery it is omap3 or not, we can build pmu.o into

One face detection IP[1] is integared inside OMAP4 SoC, so
introduce this driver to make face detection function work
on OMAP4 SoC.
This driver is platform independent, so in theory can
be used to drive same IP module on other platforms.
