New ThunderX firmware incorporates modified DTB that presents
different device hierarchy. In the new device tree, MDIO
devices are below two additional buses that oddly hang on
PCI bridge.

Fix finding appropriate BGX node in DTB and move it to a separate function
Search for BGX node in DTS in two ways:
1. Try to find it uder root node first
2. If not found under root, find the top level PCI bridge node
and search all nodes below it until appropriate BGX node is found.
Move search code to another function to make the code more clear.
Remove unused variable by the way.

EHCI: Make core reset and port speed reading more generic.
Use driver settable callbacks for handling of:
- core post reset
- reading actual port speed
Typically, OTG enabled EHCI cores wants setting of USBMODE register,
but this register is not defined in EHCI specification and different
cores can have it on different offset.
Also, for cores with TT extension, actual port speed must be determinable.
But again, EHCI specification not covers this so this patch provides
function for two most common variant of speed bits layout.

SMP support for ARMv6/v7 HW watchpoints
Use per-CPU structure to store HW watchpoints registers state
for each CPU present in the system. Those registers will be restored
upon wake up from the STOP state if requested by the debug_monitor
code. The method is similar to the one introduced to AMD64.
We store all possible 16 registers for HW watchpoints
(maximum allowed by the architecture).
HW breakpoints are not maintained since they are used for single
stepping only.

This fixes a bug in UFS2 exported NFS volumes. An NFS client can
crash a server that has exported UFS2 by presenting a filehandle
with an inode number that references an uninitialized inode in a
cylinder group. The problem is that UFS2 only initializes blocks
of inodes as they are first allocated and ffs_fhtovp() does not
validate that the inode is in a range of inodes that have been
initialized. Attempting to read an uninitialized inode gets random
data from the disk. When the kernel tries to interpret it as an
inode, panics often arise.

The bread() function was inconsistent about whether it would return
a buffer pointer in the event of an error (for some errors it would
return a buffer pointer and for other errors it would not return a
buffer pointer). The cluster_read() function was similarly inconsistent.
Clients of these functions were inconsistent in handling errors.
Some would assume that no buffer was returned after an error and
would thus lose buffers under certain error conditions. Others would
assume that brelse() should always be called after an error and
would thus panic the system under certain error conditions.
To correct both of these problems with minimal code churn, bread()
and cluster_write() now always free the buffer when returning an
error thus ensuring that buffers will never be lost. The brelse()
routine checks for being passed a NULL buffer pointer and silently
returns to avoid panics. Thus both approaches to handling error
returns from bread() and cluster_read() will work correctly.
Future code should be written assuming that bread() and cluster_read()
will never return a buffer with an error, so should not attempt to
brelse() the buffer when an error is returned.

When finding the physical address of a device allow intermediate addresses
to be 64-bit on 32-bit architectures. It is not uncommon for device trees
to use the upper 32-bits to store what effectively is an index into the
parent ranges property. In this case, when running with a 32-bit bus_addr_t
and bus_size_t, we would previously truncate the address, this may then
incorrectly match the wrong range, and return the wrong address.
