This moves the U300 timer code to look up its clock rate from the
clock framework as is apropriate and also switches it over to use

event.

This fixes a regression due to the new apb_pclk stuff in the U300
platform, makes it run by splitting the apb clock off the single
UART clocks. For the MMCI and PL022 clocks we don't split them:
these are actually hardwired to the same clock terminal and will
thus simply have a double reference count and will be referenced
twice.

We also move clock registration to .init_irq() so they are
available early enough for probing to be successful and remove the
earlier quirk to clock primecells during PrimeCell registration.

On versions of the Cortex-A9 prior to r2p0, performing TLB invalidations by
ASID match can result in the incorrect ASID being broadcast to other CPUs.
As a consequence of this, the targetted TLB entries are not invalidated
across the system.

This workaround changes the TLB flushing routines to invalidate entries
regardless of the ASID.

This change addresses the following situation:

- Thread A acquires the rwsem for read
- Thread B tries to acquire the rwsem for write, notices there is already
  an active owner for the rwsem.
- Thread C tries to acquire the rwsem for read, notices that thread B already
  tried to acquire it.
- Thread C grabs the spinlock and queues itself on the wait queue.
- Thread B grabs the spinlock and queues itself behind C. At this point A is
  the only remaining active owner on the rwsem.

In this situation thread B could notice that it was the last active writer
on the rwsem, and decide to wake C to let it proceed in parallel with A
since they both only want the rwsem for read.

Previously each waiting thread added a bias of RWSEM_WAITING_BIAS.  With
this change, the bias is added only once to indicate that the wait list is
non-empty.

This has a few nice properties which will be used in following changes:
- when the spinlock is held and the waiter list is known to be non-empty,
  count < RWSEM_WAITING_BIAS  <=>  there is an active writer on that sem
- count == RWSEM_WAITING_BIAS  <=>  there are waiting threads and no
                                     active readers/writers on that sem

In __rwsem_do_wake(), we can skip the active count check unless we come
there from up_xxxx().  Also when checking the active count, it is not
actually necessary to increment it; this allows us to get rid of the read
side undo code and simplify the calculation of the final rwsem count
adjustment once we've counted the reader threads to wake.

The basic observation is the following.  When there are waiter threads on
a rwsem and the spinlock is held, other threads can only increment the
active count by trying to grab the rwsem in down_xxxx().  However
down_xxxx() will notice there are waiter threads and take the down_failed
path, blocking to acquire the spinlock on the way there.  Therefore, a
thread observing an active count of zero with waiters queued and the
spinlock held, is protected against other threads acquiring the rwsem
until it wakes the last waiter or releases the spinlock.

This is in preparation for later changes in the series.

In __rwsem_do_wake(), the first queued waiter is checked first in order to
determine whether it's a writer or a reader.  The code paths diverge at
this point.  The code that checks and increments the rwsem active count is
duplicated on both sides - the point is that later changes in the series
will be able to independently modify both sides.

may sleep for as long as 20ms.  Caller's of msleep(1) or msleep(2), etc
are likely not to expect this quirky behavior - warn them.

When possible, sleeping is (usually) better than delaying; however, don't
bother callers of udelay < 10us, as those cases are generally not worth
the switch to usleep

Make error message say 'ERROR: do not initialise globals to 0 or NULL'
rather than 'ERROR: do not initialise externals to 0 or NULL'.  Makes more
sense in the context since there is an extern keyword in C and that is a
global declaration within the scope of the current file.
