For some reason, the value of the HPTXFSIZ register was built in the
ptxfsiz variable, while there was also a hptxfsiz variable availble.
Better just use that and remove the (now unused) ptxfsiz variable.

The value of the hcchar register is built from individual values by
shifting and masking. Before, the debug output extracted the individual
values out of the complete hcchar register again by doing the reverse.
This commit makes the debug output use the original values instead.

One debug message got removed, since it would always print a fixed value
of zero.

This line extracted the available queue space without properly shifting
it. Since the code only cared wether it was zero or not, it worked as
expected without the shift, but adding shift makes the code cleaner.

While we're here, store the result in a helper variable that was already
declared to increase readability a bit more.

Various register fields wider than one bit have constants defined for
their value. Previously, these registers would define the values as they
appear in the register, so shifted to the right to the position the
value appears in the register.

This commit changes those constants to their natural values (e.g, 0, 1,
2, etc.), as they are after shifting the register value to the right.
This also changes all relevant code to shift the values before comparing
them with constants.

This has the advantage that the values can be stored in smaller
variables (now they always require a u32) and makes the handling of
these values more consistent with other register fields that represent
natural numbers instead of enumerations (e.g., number of host channels).

Previously, the max_packet_count could be set to 1 << x, where x is the
number of bits available (width + 4 in the code). Since 1 << x requires
x + 1 bits to represent, this will not work. The real maximum value is
(1 << x) - 1. This value is already used the default when the set value
is invalid, but the upper limit for the set value was off-by-one.

This change makes the check the same as the one for max_transfer_size,
which was already correct.

A generic set of FIFOSIZE_* constants is defined which applies to all
fifo size and offset registers. It is already used for both the
GNPTXFSIZ and HPTXFSIZ registers, but it applies to DPTXFSIZN as well.
Some of these also had specific constants defined. This patch removes
the specific constants and documents to use the generic constants.

Note that the removed constants weren't actually used. Instead, most of
the related code uses hardcoded masks and shifts. But given that
subsequent patches will be moving that code around and introducing the
constants in the process, this patch leaves those untouched.

Also note that the GRXFSIZ register also contains a fifo size, but
there is no corresponding start address register (it is always the first
fifo in memory), the layout of the GRXFSIZ register is different and
cannot use the same constants.

The problem is due to improper settings for some of the EFUSE_XXX defines such that
EFUSE_MAP_SIZE was larger than the sizes of the marked arrays. Thanks to
Fengguang Wu for helping me understand the root cause.

Merge tag 'iio-for-3.12c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Third set of new drivers, cleanups and features for IIO in the 3.12 cycle.

New drivers

1) Bosh BMA180 accelerometer + a new sysfs abi element, power_mode to
   allow for device that trade off accuracy and power usage.

Cleanups

1) Another lot of devm_iio_device_alloc patches
2) An code ordering bug in the twl6030 driver introduced earlier in this
   cycle.

New features

1) at91 adc driver rework to support a wider range of parts and drop
   the necessity for some of the current device tree elements.  This is
   a precursor to introducing input support which is still under review.

For at91 boards, there are different IPs for adc. Different IPs has different
STARTUP & PRESCAL mask in ADC_MR.
