CATS sets its swizzle function to zero, which at the moment means
that no swizzling is required. Make this explicit for CATS.

Some platforms mark their hw_pci structure as __initdata, which means
it will be discarded after init time. Storing pointers to __initdata
in long lived data structures is a potential source of problems, and
in this case, sys->hw is unused apart from its initialization.
So, lets remove this member and its initializer.

Ensure that the USB ULPI signals are not tri-stated, and have no pull-
up or pull-down.
Ensure that the pingroup hosting the USB ULPI reset signal (GPIO PV0 or
PV1 depending on the board, so UAC) is not tri-stated, and has no pull-
up or pull-down.
This change appears larger than it is due to the grouping and sorting of
the pin configuration data.

ULPI PHYs have a reset signal, and different boards use a different GPIO
for this task. Add a property to device tree to represent this.
I'm not sure if adding this property to the EHCI controller node is
entirely correct; perhaps eventually we should have explicit separate
nodes for the various PHYs. However, we don't have that right now, so this
binding seems like a reasonable choice.

Not all boards use GPIO_PV0 as the ULPI PHY reset signal. Instead of
hard-coding this GPIO into devices.c, make the board files set it
explicitly. This will allow the PHY code to differentiate between set and
unset values, and hence know when to read the value from device tree.

pll_p_out4 is used on all/most Tegra boards to drive the cdev2 output pin
to provide a reference clock to a ULPI USB PHY. This reference clock must
run at 24MHz, and the cdev2 output has no additional dividers.

Commit 40f9cf0 "ARM: tegra: reparent sclk to pll_c_out1" changed the
rate of hclk. Since pclk is derived from that, and only has integer
dividers, the pclk rate needs to change in the same fashion, from 54MHz
to 60MHz.

pll_p_out4 needs to be used for other purposes. Reparent sclk so that
it runs from pll_c. Change sclk's rate to 120MHz from 108MHz since this
is the lowest precise rate that can be achieved by dividing the pll_c
rate without reducing the sclk rate. (600/5=120, 600/5.5=109.0909...,
600/6=100).

pll_c will be used as a clock source. Fill in tegra_pll_c_freq_table[]
so that it's possible to explicitly initialize the PLL.
NVIDIA's downstream nv-3.1 kernel and the ChromeOS kernel have different
pll_c tables. nv-3.1 contains entries for 522MHz and 598MHz output,
whereas the ChromeOS kernel contains entries for 600MHz output. I chose
to upstream the ChromeOS values for now, since the 600MHz rate appears
to match the default rate of this PLL when the HW boots, and it's not
clear to me why 522 or 598MHz are more useful.

We used to pass the timer clock directly to mxc_timer_init. We
should instead request the correct clock. This is an intermediate
step: For now we request the clock in the timer code when NULL
is passed as clock.
Also, the gpt on some i.MX have an additional ipg clock which can
be gated. Request and enable this.

This patch tries to fix the problem of page fault exception
caused by accessing nmiaction structure in nmi if kmemcheck
is enabled.
If kmemcheck is enabled, the memory allocated through slab are
in pages that are marked non-present, so that some checks could
be done in the page fault handling code ( e.g. whether the
memory is read before written to ).
As nmiaction is allocated in this way, so it resides in a
non-present page. Then there is a page fault while the nmi code
accessing the nmiaction structure, which would then cause a
warning by WARN_ON_ONCE(in_nmi()) in kmemcheck_fault(), called
by do_page_fault().
This significantly simplifies the code as well, as the whole
dynamic allocation dance goes away.
v2: as Peter suggested, changed the nmiaction to use static
storage.
v3: as Peter suggested, use macro to shorten the codes. Also
keep the original usage of register_nmi_handler, so users of
this call doesn't need change.
