usb: ohci: Remove unnecessary delays from hc_start and power power-on paths

The usb spec says that we must wait a minimum amount of time after port
power on (exact time is in the hub descriptor), this is something which
we must not only do for root ports but also for external hub ports, which
is why the common usb_hub code already waits a full second after powering
up ports. Having a separate wait for just the root hub in the ohci-hcd
code only leads to doing the waiting twice for the root ports, so drop the
wait from the ohci-hcd code.

usb: ohci: Do not resubmit and leak urbs for interrupt packets

The u-boot usb code uses polling for all endpoints, including interrupt
endpoints, so urbs should never be automatically resubmitted.

usb: ohci: Do not resubmit and leak urbs for interrupt packets

The u-boot usb code uses polling for all endpoints, including interrupt
endpoints, so urbs should never be automatically resubmitted.

This also fixes a leak of the urb, as submit_int_msg() did not check if
an already re-submitted urb exists before creating a new one.

include: move various macros to include/linux/kernel.h

U-Boot has imported various utility macros from Linux
scattering them to various places without consistency.

In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN,
container_of, DIV_ROUND_UP, etc.
In include/linux/compat.h are min_t, max_t, round_up, round_down,
etc.
We also have duplicated defines of min_t in some *.c files.

Moreover, we are suffering from too cluttered include/common.h.

This commit moves various macros that originate in
include/linux/kernel.h of Linux to their original position.

Note:
This commit simply moves the macros; the macros roundup,
min, max, min2, max3, ARRAY_SIZE are different
from those of Linux at this point.

usb: create common header virtual root hub descriptors

Many USB host controller drivers contain almost identical copies of the
same virtual root hub descriptors. Put these into a common file to avoid
duplication.

Note that there were some very minor differences between the descriptors
in the various files, such as:

- USB 1.0 vs. USB 1.1
- Manufacturer/Device ID
- Max packet size
- String content

I assume these aren't relevant.
