7a1e6fb1c6 hwspinlock: qcom: Allow mmio usage in addition to syscon 
In modern Qualcomm platforms the mutex region of the TCSR is forked off
into its own block, all with a offset of 0 and stride of 4096, and in
some of these platforms no other registers in this region is accessed
from Linux.

So add support for directly memory mapping this register space, to avoid
the need to represent this block using a syscon.

ed0611a604 hwspinlock: qcom: Use devm_hwspin_lock_register() to register hwlock controller 
Use devm_hwspin_lock_register() to register the hwlock controller instead of
unregistering the hwlock controller explicitly when removing the device.

98ec52ad81 hwspinlock: qcom: Remove redundant PM runtime functions 
Since the hwspinlock core has changed the PM runtime to be optional, and
the Qualcomm hardware spinlock has no pm runtime requirement, thus remove
these redundant PM runtime functions.

bd5717a463 hwspinlock: qcom: Correct msb in regmap_field 
msb of the regmap_field was mistakenly given the value 32, to set all bits
in the regmap update mask; although incorrect this worked until 921cc294,
where the mask calculation was corrected.
