This fixes the loop delay when using a hw watchdog.

In case a watchdog is used that accesses CPU registers,
the defined delay of 20us in a tight loop will cause a
huge delay in the actual timeout seen. This is caused
by the fact that udelay will inheritantly call WATCHDOG_RESET.
Together with the omap wdt implementation, the seen timeout increases up to
around 30s. This makes the loop very slow and causes long
delays when using the modem.

Instead, implement the 2 sec loop by using the timer interface to know
when to break out of the timeout loop. Watchdog kicking is taken care of
by getc().

linux/compat.h: Properly implement ndelay fallback

Commit c68c62 ("i2c: mvtwsi: Make delay times frequency-dependent")
extensively used the ndelay function with a calculated parameter
which is dependant on the configured frequency of the I2C bus. If
standard speed is employed, the parameter is usually 10000 (10000ns
period length for 100kHz frequency).

But, since the arm architecture does not implement a proper version of
ndelay, the fallback default from include/linux/compat.h is used,
which defines every ndelay as udelay(1). This causes problems for
slower speeds on arm, since the delay time is now 9us too short for
the desired frequency, which leads to random failures of the I2C
interface.

To remedy this, we implement a proper, parameter-aware ndelay fallback
for architectures that don't implement a real ndelay function.

arm: sunxi: do not force USB for arch-sunxi

Currently, USB is forced-enabled for the sunxi familly, and there is no
way to disable it.

However, USB takes a long time to initiliase, delaying the boot by up to
5 seconds (without any USB device attached!). This is a very long delay,
especially in cases where USB booting is not wanted at all, and where
the device is expected to boot relatively often (even in production).

Change the way the dependencies are handled, by only forcibly selecting
USB when CONFIG_DISTRO_DEFAULTS ("defaults suitable for booting general
purpose Linux distributions") is set. This option defaults to y for the
sunxi familly, so the current default behaviour is kept unchanged. Users
interested in boot time and/or size will be able to disable this to
further disable USB.

With USB disabled, the time spent in U-Boot before handing control to
the Linux kernel is about 1s now, down from ~5s (Nanopi Neo, sunxi H3).
