5e49c57956 ipq806x: Add support for linux-4.4
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.

6b775f4517 ipq806x: add hwspinlock support
This change cherry-picks the following 3 changes from linux-next:
*fb7737 hwspinlock/core: add device tree support
*19a0f6 hwspinlock: qcom: Add support for Qualcomm HW Mutex block
*bd5717 hwspinlock: qcom: Correct msb in regmap_field

We're also adding a patch to add the hardware spinlock device nodes on
IPQ806x platforms (033-soc-qcom-Add-sfbp-device-to-IPQ806x-dts.patch).

0f7de49fa3 ipq806x: fix freeze in PCIe code when booting with an old u-boot
Old bootloader (same ones which have DT disabled) don't perform any PCIe
initialization. The consequence is a freeze during PCIe bring-up on
these old u-boot. Same kernel with a newer bootloaders works fine as
they contain the corresponding PCIe init code.

In this change, we'll add the missing init and make sure the kernel
doesn't rely on some preexisting init to get PCIe to work. That includes
the following changes:
*GPIOs: set function & drive strength
*Clocks: add init code for aux & ref clocks
*PCIe driver: additional init of the hardware controller

Tested 3.18 and 4.1 on an AP148 with bootloader branch 0.0.1
