musb-new: Fix reset sequence when in host mode

This commit fixes a number of issues with the reset sequence of musb-new
in host mode:

1) Our usb device probe relies on a second device reset being done after the
first descriptors read. Factor the musb reset code into a usb_reset_root_port
function (and add this as an empty define for other controllers), and call
this when a device has no parent.

2) Just like with normal usb controllers there needs to be a delay after
reset, for normal usb controllers, this is handled in hub_port_reset, add a
delay to usb_reset_root_port.

3) Sync the musb reset sequence with the upstream kernel, clear all bits of
power except bits 4-7, and increase the time reset is asserted to 50 ms.

With these fixes an usb keyboard I have now always enumerates properly, where
as earlier it would only enumerare properly once every 5 tries.

musb-new: Fix interrupt transfers not working

For bulk and ctrl transfers common/usb.c sets udev->status = USB_ST_NOT_PROC,
but it does not do so for interrupt transfers.

musb_uboot.c: submit_urb() however was waiting for USB_ST_NOT_PROC to become 0,
and thus without anyone setting USB_ST_NOT_PROC would exit immediately for
interrupt urbs, returning the urb status of EINPROGRESS as error.

This commit fixes this, thereby also making usb_kbd.c work together with
musb_new and CONFIG_SYS_USB_EVENT_POLL.

musb-new: Use time based timeouts rather then cpu-cycles based timeouts

CPU cycle based timeouts are no good, because how long they use depends on
CPU speed. Instead use time based timeouts, and wait one second for a
device connection to show up (per the USB spec), and wait USB_TIMEOUT_MS
for various urbs to complete.

This fixes "usb start" taking for ever when no device is plugged into the
otg port.

U-Boot has imported various source files from other projects,

Something like

#ifdef __UBOOT__
[ modification for U-Boot ]
#else

#endif

is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

board/compulab/common/Makefile
board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because
they are new:

include/configs/am335x_igep0033.h
include/configs/omap3_igep00x0.h
