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).

+Subject: [PATCH] hwspinlock/core: add device tree support
+
+This patch adds a new OF-friendly API of_hwspin_lock_get_id()
+for hwspinlock clients to use/request locks from a hwspinlock
+device instantiated through a device-tree blob. This new API
+can be used by hwspinlock clients to get the id for a specific
+lock using the phandle + args specifier, so that it can be
+requested using the available hwspin_lock_request_specific()
+API.

+Subject: [PATCH] hwspinlock/core: add device tree support
+
+This patch adds a new OF-friendly API of_hwspin_lock_get_id()
+for hwspinlock clients to use/request locks from a hwspinlock
+device instantiated through a device-tree blob. This new API
+can be used by hwspinlock clients to get the id for a specific
+lock using the phandle + args specifier, so that it can be
+requested using the available hwspin_lock_request_specific()
+API.

+From c7c482da19a5e4ba7101198c21c2434056b0b2da Mon Sep 17 00:00:00 2001
+From: Mathieu Olivari <mathieu@codeaurora.org>
+Date: Thu, 13 Aug 2015 09:45:26 -0700
+Subject: [PATCH 1/3] ARM: qcom: add SFPB nodes to IPQ806x dts
+
+Add one new node to the ipq806x.dtsi file to declare & register the
+hardware spinlock devices. This mechanism is required to be used by
+other drivers such as SMEM.
