This patch teaches the i2c-sh_mobile driver to make use of wait irqs.
Without this patch only dte irqs are used which may lead to overruns
and cases of missing stop and extra bytes being read on the i2c bus.
Use of wait irqs forces the hardware to pause and wait until the cpu
is ready. Polling is also reworked in this patch to fix ms delay issues.
Verified with bus analyzer and tested on MigoR and AP325RXA boards.

This patch fixes a problem within the SH implementation of resume_kernel code,
that implements in assembly the bulk of preempt_schedule_irq function without
taking care of the extra code needed to handle the BKL preemptible.
The patch basically consists of removing this asm code and calling the common
C implementation (see kernel/sched.c) as other archs do.
Another change is the missing 'cli' macro invocation at the beginning of
the resume_kernel.

As all the infrastructure for multiple transmit queues already exists
in the driver, this patch is entirely trivial.
The individual transmit queues are still serialised by the driver's
per-port private spinlock, but that will disappear (i.e. be replaced
by the per-subqueue ->_xmit_lock) in a subsequent patch.

Delete a couple of unused and uninteresting interrupt source mask bits:
- The receive resource underrun interrupt sources are uninteresting
because if we are in out-of-memory mode, we are already dealing with
the issue, and we don't need the hardware to remind us again that we
are out of memory.
- The LINK and PHY interrupt sources can be coalesced into one define,
since we always use them together.
- The transmit resource underrun interrupt source can be disabled since
we never activate the head descriptor of a paged skb until the
fragments are all activated, so transmit underrun during a packet
should never happen.
- The INT_EXT_TX_0 define is never used.

Currently, there are two different fields in the
mv643xx_eth_platform_data struct that together describe the PHY
address -- one field (phy_addr) has the address of the PHY, but if
that address is zero, a second field (force_phy_addr) needs to be
set to distinguish the actual address zero from a zero due to not
having filled in the PHY address explicitly (which should mean
'use the default PHY address').
If we are a bit smarter about the encoding of the phy_addr field,
we can avoid the need for a second field -- this patch does that.

By having the receive out-of-memory handling timer schedule the napi
poll handler and then doing oom processing from the napi poll handler,
all code that touches receive state moves to napi context, letting us
get rid of all explicit locking in the receive paths since the only
mutual exclusion we need anymore at that point is protection against
reentering ourselves, which is provided by napi synchronisation.

If the platform code has passed us the IRQ number of the mv643xx_eth
top-level error interrupt, use the error interrupt to wait for SMI
access completion instead of polling the SMI busy bit, since SMI bus
accesses can take up to tens of milliseconds.

Since commit 81600eea98 ("mv643xx_eth:
use auto phy polling for configuring (R)(G)MII interface"),
mv643xx_eth no longer does SMI accesses from interrupt context. The
only other callers that do SMI accesses all do them from process
context, which means we can switch the PHY lock from a spinlock to a
mutex, and get rid of the extra locking in some ethtool methods.

The problem of finger tracking, i.e., when to switch focus from one
finger to another on the trackpad, has been improved by utilizing more
information from the bcm5974 chip output. This results in less pointer
hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.
