This patch reverses the condition in two if
statements in CopyBufferToControlPacket to
place Adapter->bShutStatus and
Adapter->idleMode to the left of the equal
"==" sign, and TRUE to the right of
the equal "==" sign. This was done for
readability purposes.

This patch cleans up the code in function
CopyBufferToControlPacket. Several things are
being done here: (1) remove the null
initialization from variable cntrl_buff, (2)
reverse the if statement to check if cntrl_buff
is null; if so, then write debug statement and
return -ENOMEM error code, and (3) indent the
code properly.

This patch removes an unneeded do while loop which
sends a control message to bcm usb device. In this case,
the loop executes once because usRetries is
initialized to zero. After the first iteration
this variable will be 1. Therefore, the statement:
"usRetries < MAX_RDM_WRM_RETIRES" will evaluate to
false causing the do while statement to execute
once because MAX_RDM_WRM_RETIRES is equal to 1.

Previously the *_phys fields were of type ipack_addr_space, which use
void pointers to refer to memory addresses. Since the *_phys fields
refer to unmapped memory, this is not correct. Introduce a new struct
ipack_region (which uses phys_addr_t to refer to the start of a region)
and use that as a replacement for struct ipack_addr_space.
struct ipack_region is defined in ipack.h because it is planned to later
expose the physical addressed to the IPack Module drivers.

For ADCs or DACs the denominator for fractional types often is a power of two.
In this case we can use a shift operation instead of the rather expensive 64 bit
division. This patch adds a new fractional type which expects the denominator to
be specified as the log2 of the actual denominator. E.g. for ADCs and DACs this
will usually be the number of significant bits.

The driver has not been building for some time after the
irq_to_gpio function has been removed from the kernel.
The only board in the upstream kernel that provides
this device is the "Stargate 2", which is also maintained
by Jonathan Cameron. Rather than working around the problem
by adding new platform data for this driver, this patch
uses the of_gpio framework to get to the gpio number.
However, the stargate2 code does not (yet) use DT based
probing, so it is still broken, but at least building
allyesconfig works again.
