Remove the the redundant 'of_match_ptr' macro to fix below warning
when the CONFIG_OF is not selected.
All warnings:

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

Since the hwspinlock core has changed the PM runtime to be optional, and
the SIRF hardware spinlock has no pm runtime requirement, thus remove
these redundant PM runtime functions.

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together, which can simpify the code.

Use the appropriate SPDX license identifier in the CSR's SIRF hardware
spinlock driver source file and drop the previous boilerplate license text.

Add hwspinlock support for the CSR atlas7 SoC.
The Hardware Spinlock device on atlas7 provides hardware assistance
for synchronization between the multiple processors in the system
(dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).
