Add push of PV variable to the petalinux make.
m86: ignore empty script directories
Added new filter definition and command line example script.

New filter definition wb_wimax has 64 taps to support 56 MHz sample rate.
New command line example script wimax_example shows how to use sh scripting to initialize the AD9361 tool and dma_streamer_app
Merge branch 'sdrdc-devel' of https://github.com/silverbullettechnology/sdrdc-build into sdrdc-devel
Fix common.h include

- Moved to library include path
- Included from main public header
Added example application for using ad9361 and asfe_ctl libraries.

Added sbt_ad9361_example application.
Updated asfe_ctl library with wrapper functions.
Updated ad9361 scripts

Removed depreciated scripts from ad9361 script folder
Updated sbt_ad9361_example application
added startup script to configure ad9361 devices sample rates and sleep mode.
Changes to support AMP BSP

- Disable CONFIG_CC_OPTIMIZE_FOR_SIZE to use -O2 optimization
- Add a SBT_BSP select in Config for normal "SDRDC" vs AMP "SDRDC-AMP" BSP
- Remove Kconfig.lib.auto/Makefile.lib.auto generation now that Petalinux _defconfig
  works, was causing lib rebuild problems with readline.
- Revise setup/defconfig logic:
  - Move mrproper/defconfig from build to reset step
  - Call manually with reset target, or from setup target based on flag file
- Calculate uImage LOADADDR based on CONFIG_PHYS_OFFSET if enabled and >0, for AMP
- Change Petalinux "make dep" on kernel sources to "make prepare"
- Remove various verbose and debug messages

m58: New files for FreeRTOS support

- Add sbt/hardware tree for SDRDC hardware description when setting up FreeRTOS BSP in
  Xilinx SDK
- SDRDC-AMP BSP for preconfigured Petalinux side of AMP recipe
- Prebuilt FreeRTOS application for testing
m58: DTS and config changes for FreeRTOS AMP
m88: Cleanup cut1/cut2 legacy

- Remove various cut1/cut2 config and ifdef left from testing pre-production boards
- Clean up some comments and debug messages
m87: Startup with AD9361s in SLEEP mode
m80: Key-triggered transmit events

- Add explicit triggering modes and revise documentation:
  - "once" mode for single transaction, cleanup, and exit
  - "press" mode for one transaction per keypress
  - "cont" mode for continuous transaction until keypress
- "press" mode can be specified with repetitions per run like "cont" mode
- Show stats per each run in "press" mode, unless suppressed with -S
- Made examples printed in usage copy/pastable with canned waveform filename
m89: interpret enum names consistently
m91: enable example AD9361 app by default
Use new library API for checking active channels
m90, m81: DSA check and control of ENSM state

- Check current ENSM mode and FDD enable for each enabled ADI part before DMA
- If ADI is in an active mode which supports user's DMA direction, proceed
- If ADI is configured for FDD but in sleep, wait, or alert, set mode to FDD, unless user
  has given -M switch to forbid mode switching, before starting DMA
- If user didn't give -M switch and we switched into FDD before starting DMA, switch to
  sleep mode after DMA
New PL image 5x for Ethernet testing
Updated sleep mode scripts and temperature measurement function

Startup script was modified to load the wimax example filters as well as set the ad9361 devices in sleep mode to conserve power.
Temperature measurement function was modified to provide more accurate readings across multiple sample rates.  Note that currently it wil only work correctly with the driver set in FDD mode.
