core: gic: add gic_init_donate_sgi_to_ns()

Adds gic_init_donate_sgi_to_ns() which changes a secure SGI to become
non-secure.

Secure world currently has a few SGIs to spare while normal world
typically have reserved each of the non-secure SGIs for different
purposes.

In case another non-secure SGI is needed secure world can donate one of
its unused SGIs. This configuration will then deviate from the standard
GIC configuration where SGI ID0-ID7 are non-secure and ID8-ID15 are
secure.

Platforms using gic_init_donate_sgi_to_ns() should also use
gic_init_per_cpu() instead of the deprecated gic_cpu_init().

The Hisilicon QM is a Queue Management module.
In order to unify the interface between accelerator and software,
a unified queue management module QM is used to interact with software.
Each accelerator module integrates a QM. Software issues tasks to the SQ
(Submmision Queue),and the QM obtains the address of the SQE (Submmision
Queue Element). The BD (Buffer Description, same as SQE) information is
sent to the accelerator. After the task processing is complete, the
accelerator applies for a write-back address from the QM to write back
the SQ.

Update PWR driver to configure High Speed Low Voltage mode for
fixed VDD supplied domain thanks to recently introduced SYSCFG HSLV
API functions. This configuration must be appleid at boot time and
when resuming from a system low power state.

This configuration depends on VDD voltage level. It can protected by
a OTP bit (HW2 bit 13) described in the chip reference manual for when
VDD is supplied with a voltage below 2.5V. As stated in the chip
reference manual, enabling HSLV mode with a VDD voltage level above
2.7V may be destructive hence the driver panics in such case.
