At present bootstage only supports U-Boot proper. But SPL can also consume
boot time so it is useful to have the record start there.
Add bootstage support to SPL. Also support stashing the timing information
when SPL finishes so that it can be picked up and reported by U-Boot
proper. This provides a full boot time record, excluding only the time
taken by the boot ROM.

At present we don't allow use of bootstage before driver model is running.
This means we cannot time the init of driver model itself.
Now that bootstage requires its own board-specific timer, we can move its
init to earlier in the sequence, both before and after relocation.

At present bootstage has a large array with all possible bootstage IDs
recorded. It adds times to the array element indexed by the ID. This is
inefficient because many IDs are not used during boot. We can save space
by only recording those IDs which actually have timestamps.
Update the array to use a record count, which increments with each
addition of a new timestamp. This takes longer to record a time, since it
may involve an array search. Such a search may be particularly expensive
before relocation when the CPU is running slowly or the cache is off. But
at that stage there should be very few records.

At present bootstage uses the data section of the image to store its
information. There are a few problems with this:
- It does not work on all boards (e.g. those which run from flash before
relocation)
- Allocated strings still point back to the pre-relocation data after
relocation
Now that U-Boot has a pre-relocation malloc() we can use this instead,
with a pointer to the data in global_data. Update bootstage to do this and
set up an init routine to allocate the memory.
Now that we have a real init function, we can drop the fake 'reset' record
and add a normal one instead.
Note that part of the problem with allocated strings remains. They are
reallocated but this will only work where pre-relocation memory is
accessible after relocation.

At present we provide a default version of this function for use by
bootstage. However it uses the system timer and therefore likely requires
driver model. This makes it impossible to time driver-model init.
Drop the function and require boards to provide their own. Add a sandbox
version also. There is a default implememtation in lib/time.c for boards
which use CONFIG_SYS_TIMER_COUNTER.

This deassert counter allow to manage "shared" reset lines
encountered in some specific case. On STiH410 SoC, DWC3,
EHCI and OHCI are all using a respective PHY, but all of
these PHYs shared a "global" reset.
Currently, during command "usb stop", all host controller are
stopped (XHCI, EHCI and OHCI). XHCI is first shutdowned, which
means that PHY global reset is asserted. Then EHCI is shutdowned,
but its PHY reset has already been asserted which make handshake()
call failed in ehci_shutdown().
This counter allows to really assert a reset lines only when the
"last" user is asserting it.
