In rxtx.c many calls to BBvCaculateParameter are not endian

Correct the endian in BBvCaculateParameter.
In card.c: CARDvSetRSPINF pwPhyLen points to awLen and is
manually applied to abyData. Because it is now endian
corrected put_unaligned is needed to correct it.
In rxtx.c remove were endian is corrected.
This allows to merge BBvCalculateParameter *pwPhyLen,*pbyPhySrv

In dt282x_ai_insn_read() we call this macro like:

Because the if statement doesn't have curly braces it means we always
return -ETIME and the function never succeeds.

Jonathan writes:
Second round of new drivers, features and cleanups for IIO in the 3.12 cycle.
New driver:
1) tmp006 IR thermopile driver. This is an unusual temperature sensor
and was taken in to IIO with the knowledge and agreement of a hwmon
maintainer.
It measures remote temperature using infrared emissions.
I guess taking this may mean we have to fight off submissions of
devices much more suited to hwmon but such is life and we end up
doing this from time to time already.
2) twl6030 adc driver.
Cleanups:
1) More devm_* cleanups following on from the introduction of
devm_iio_device_alloc. Mostly an heroic effort from
Sachin Kamat!
2) Introduce devm_iio_trigger_alloc etc to handle trigger
allocation and deallocation in a managed fashion. There
aren't as many instances of triggers as devices, but this
will allow futher reduction in error patch complexity in
some of our most complex drivers making it a very good thing.
3) Trivial removal of unused defines in adjd_s311
4) Drop some write_raw_get_fmt callbacks where they were only
returning the default value.
5) Change mxs-lradc realbits to 12. Whilst an 18bit register
is used on the device, in its current mode only 12 bits of
useful data are returned. For now the packing is unchanged
in the buffer and this change mainly effects the input support
in the driver.
Add a resource managed devm_iio_trigger_alloc()/devm_iio_triger_free()
to automatically clean up triggers allocated by IIO drivers, thus
leading to simplified IIO drivers code.

The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC,
known also as Phoenix and PhoenixLite.
The TWL6030 and TWL6032 have GPADC with 17 and 19 channels
respectively. Some channels have current source and are used for
measuring voltage drop on resistive load for detecting battery ID
resistance, or measuring voltage drop on NTC resistors for external
temperature measurements. Some channels measure voltage, (i.e. battery
voltage), and have voltage dividers, thus, capable to scale voltage.
Some channels are dedicated for measuring die temperature.
Some channels are calibrated in 2 points, having offsets from ideal
values kept in trim registers. This is used to correct measurements.
The differences between GPADC in TWL6030 and TWL6032:
- 10 bit vs 12 bit ADC;
- 17 vs 19 channels;
- channels have different purpose(i.e. battery voltage
channel 8 vs channel 18);
- trim values are interpreted differently.
Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K,
Girish S Ghongdemath.

The LRADC virtual channels have an 18 bit field to store the sum of up
to 2^5 accumulated samples. The read_raw function however only operates
over a single sample (12 bit resolution).
In order to use this field for scaling operations, we need it to be the
exact resolution value of the LRADC.
Besides, the driver was using an 18 bit mask (LRADC_CH_VALUE_MASK) to
report touch coordinates to userland. A 12 bit mask should be used instead
or else the touch libraries will expect a coordinates range between 0
and 0x3ffff (18 bits), instead of between 0 and 0xfff (12 bits).
