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.

*Enable SMEM MTD parser and its dependencies (SMEM & HW spinlocks) in
the kernel config
*Replaces the MTD layout in DT by the dynamic layout provided by the
SMEM parser for AP148
Using the OF based parser is still possible on platforms which have a
fixed MTD partition layout.

Previous patch 6f2905eeb6ce5ddec8d12d677e1f377a940b537b enabled ADM in
the kernel, which causes a kernel panic when accessing the SPI flash.
As a workaround, We'll disable DMA for the flash for now. It was not
enabled previously anyway so we'll just leave it as is.

These patches add support for ipq806x NAND flash controller. Most of
these are cherry-picked & backported from LKML:
*https://lkml.org/lkml/2015/8/3/16
This patch just modifies the kernel code, but doesn't change the config.
It should be harmless.
