The ATB DTB mangle code will enter an infinite loop if it encounters a
word in the command line that contains an r in the middle of the word.
Fix this by increasing ptr everytime before invoking strchr, ot avoid
finding the same r again.
This fixes booting at least on Netgear R7500v1, which contains
"ubi.mtd=rootfs" in its commandline, triggering the misbehaviour.

The command-line arguments provided by the boot loader will be
appended to a new device tree property: bootloader-args.
If there is a property "append-rootblock" in DT under /chosen
and a root= option in bootloaders command line it will be parsed
and added to DT bootargs with the form: <append-rootblock>XX.
Only command line ATAG will be processed, the rest of the ATAGs
sent by bootloader will be ignored.
This is usefull in dual boot systems, to get the current root partition
without afecting the rest of the system.

In commit "regulator: qcom: Rework to single platform device" the smb208
regulator used in IPQ8064 was left out.
Add it to that new framework and update Docs and DT accordingly.

1)Changes
- Rebased the patches for linux-4.4.7
- Added patch to fix spi nor fifo and dma support
- Added patch to configure watchdog barktime
2)Testing
Tested on IPQ AP148 Board:
a. NOR boot and NAND boot
b. ethernet network and ath10k wifi
c. ubi sysupgrade
UnTested
dwc3 usb has not been validated on IPQ board(AP148)
3)Known Issues:
Once we flash ubi image on AP148, and if we reset the board, uboot on
first boot creates PEB and LEB for dynamic sized partitions, which is incorrect
and not what linux expects which causes errors when trying to mount rootfs.
In order to test this, we can use the below steps:
a. Flash the ubi image on board and don't reset the board
b. load the kernel fit image in RAM and boot from there.
