Few cpsw related dts fixes for omaps
Recent cpsw driver changes exposed few regressions in the cpsw related
dts configuration that would be good to fix:
- Few more boards still need to be updated to use rgmii-rxid phy caused
by the fallout from commit bcf3440c6d ("net: phy: micrel: add phy-mode
support for the KSZ9031 PHY" as the rx delay is now disabled unless we
use rgmii-rxid.
- On dm814x we have been using a wrong clock for mdio that now can produce
external abort on some boards

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

On a Quadra 900/950, the ISM IOP IRQ output pin is connected to an
edge-triggered input on VIA2. It is theoretically possible that this
signal could fail to produce the expected VIA2 interrupt.
The two IOP interrupt flags can be asserted in any order but the logic
in iop_ism_irq() does not allow for that. In particular, INT0 can be
asserted right after INT0 is checked and before INT1 is cleared.
Such an interrupt would produce no new edge and VIA2 would detect no
further interrupts from the IOP. Avoid this by looping over the INT0/1
handlers so an edge can be produced.

CPUCFG is the instruction for querying processor characteristics on
newer Loongson processors, much like CPUID of x86. Since the instruction
is supposedly designed to provide a unified way to do feature detection
(without having to, for example, parse /proc/cpuinfo which is too
heavyweight), it is important to provide compatibility for older cores
without native support. Fortunately, most of the fields can be
synthesized without changes to semantics. Performance is not really big
a concern, because feature detection logic is not expected to be
invoked very often in typical userland applications.
The instruction can't be emulated on LOONGSON_2EF cores, according to
FlyGoat's experiments. Because the LWC2 opcode is assigned to other
valid instructions on 2E and 2F, no RI exception is raised for us to
intercept. So compatibility is only extended back furthest to
Loongson-3A1000. Loongson-2K is covered too, as it is basically a remix
of various blocks from the 3A/3B models from a kernel perspective.
This is lightly based on Loongson's work on their Linux 3.10 fork, for
being the authority on the right feature flags to fill in, where things
aren't otherwise discoverable.

CP0.Config6 is a Vendor-defined register whose bits definitions are
different from one to another. Recently, Xuerui's Loongson-3 patch and
Serge's P5600 patch make the definitions inconsistency and unclear.
To make life easy, this patch tidy the definition up:
1, Add a _MTI_ infix for proAptiv/P5600 feature bits;
2, Add a _LOONGSON_ infix for Loongson-3 feature bits;
3, Add bit6/bit7 definition for Loongson-3 which will be used later.
All existing users of these macros are updated.

The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to
page table entry to access srmmu_nocache_pool.
But since sparc32 has only three actual page table levels, pgd, p4d and
pud are essentially the same thing and pgd_offset() and p4d_offset() are
no-ops, the __nocache_fix() should be done only at PUD level.
Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it
only for PUD and lower levels.
