b914811524 iwlagn: allow up to uCode API 6 for 6000 devices
Since the uCode hasn't been released (yet?),
warn only if using older than API 4, but load
anything up to API 6.

f02c2fd383 iwlagn: dynamically allocate & reflect calibration data
This makes handling the calibration data more generic
and no longer requires updating IWL_CALIB_MAX when a
new uCode comes with more calibration packets. Since
we just copy the data back, there's also no need for
understanding which calibration we received -- we can
just reflect it back to the runtime uCode.

93b64105e5 iwlagn: remove calibration knowledge
The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.

The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.

The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.

This makes new uCode work on 6000 series devices.

72bcacc2bd iwlwifi: add tm commands for indirect register access
Create new testmode commands to suppot indirect access
of peripheral register.
- IWL_TM_CMD_APP2DEV_INDIRECT_REG_READ32
- IWL_TM_CMD_APP2DEV_INDIRECT_REG_WRITE32

Meanwhile, add affix "DIRECT" into original register access
commands for better discrimination with new commands.
- IWL_TM_CMD_APP2DEV_DIRECT_REG_READ32
- IWL_TM_CMD_APP2DEV_DIRECT_REG_WRITE32
- IWL_TM_CMD_APP2DEV_DIRECT_REG_WRITE8

My compiler is dumb, but better to eliminate the warning than to have
anyone waste time evaluating this again...

Although this patch touches some of the code that will affect endian
issues on PCI hardware through drivers rtl8192ce, rtl8192se, and
rtl8192de, these have not been tested due to lack of suitable hardware.
