According to http://e2e.ti.com/support/arm/sitara_arm/f/791/t/210729 the
USB reset pulse has an undocumented duration of 200ns and during this
period the module must not be acessed.
We wait for 100us to take into account for some imprecision of the early
DELAY() loop.
This fixes the eventual 'External Non-Linefetch Abort (S)' that happens at
boot while resetting the musb subsystem.
While here, enable the USB subsystem clock before the first access.

partial_where points into the buffer that begins with buffer_start
so we need to use memmove() to handle the overlap.

Introduce a seperate phase to list all unavailable pools when listing
pools to upgrade. This avoids confusing output when displaying older
and disabled feature pools. These existing phases now silently skip
unavailable pools.
Introduce cb_unavail to upgrade_cbdata_t which enables the final
output for zpool list to correctly detail if all pools or only all
available pools where up-to-date on version / features.
Correct the type of upgrade_cbdata_t.cb_first from int -> boolean_t.
Change the pool iteration when upgrading named pools to include
unavailable pools and update upgrade_one so it doesn't try to upgrade
unavailable pools but warns about them. This allows the correct error
to be displayed as well as upgrades with available and unavailable
pools intermixed to partially complete.
Also correct some missing trailing \n's from output in upgrade_one.

exactly the same code is at the end of the nfscl_checksattr()
function that is called just before it. As such, this code
had already been executed and didn't do anything.

The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in. In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).
Clean up some whitespaces while here

This enables the use of GPIO pins as interrupt sources for kernel devices
directly attached to gpiobus (userland notification will be added soon).
The use of gpio interrupts for other kernel devices will be possible when
intrng is complete.
All GPIO pins can be set to trigger on:
- active-low;
- active-high;
- rising edge;
- falling edge.
Tested on: Beaglebone-black
code, passing a 0/1 flag that indicates which type of abort it was. This
sets the stage for unifying the handling of page faults in a single routine.

If it seems like this is getting out of hand, I quite agree. I wonder if
it's safe, here in the 21st century, to lose the distinction between C and
ASM symbols?
around so that related things are more grouped together, rewrite comments.
No functional changes, this is all so that the functional changes in the
next commit will stand out.
