This new workaround takes advantage of the per core IMR registers in GPC in
order to unmask the IRQ0, still generated by the 12bit in IOMUX_GPR register
(which now remains always set), so it can only wake up one core at the time.
Also, this entire workaround has now been moved here in TF-A, allowing the
kernel side to be minimal.
Another advantage this workaround brings is the removal of the 50us delay
(which was necessary before in gic_raise_softirq in kernel) by allowing the
core that is waking up to mask his own IRQ0 in the suspend finish callback.
One important change here is the way the cores are woken up in
dram_dvfs_handler. Since the wake up mechanism has changed from asserting the
12th bit in IOMUX_GPR and leaving the IMR1 1st bit on for each core to exactly
the reverse, that is, leaving the IOMUX_GPR 12th bit always set and then
masking/unmasking the IMR1 1st bit for each independent core, we need to use
the imx_gpc_core_wake to wake up the cores.
Also, the 50us udelay is moved to TF-A (inside imx_pwr_domain_off) from kernel
(gic_raise_softirq), since the new cpuidle workaround does not need it in order
to clean the IOMUX_GPC 12bit. For now, the udelay seems to be still needed
in order to delay the affinity info OFF for the dying core. This is something
that needs further investigation.

CPU hotplug & cpuidle have some race condition when doing CPU hotplug
stress test. different CPU cores have the chance to access the same
GPC register(A53_AD), so lock is necessary to do exlusive access.

The i.MX8M Mini is new SOC of the i.MX8M family. it is
focused on delivering the latest and greatest video and
audio experience combining state-of-the-art media-specific
features with high-performance processing while optimized
for lowest power consumption. The i.MX 8M Mini Media Applications
Processor is 14nm FinFET product of the growing i.MX8M family
targeting the consumer & industrial market. It is built in 14LPP
to achieve both high performance and low power consumption
and relies on a powerful fully coherent core complex based on
a quad Cortex-A53 cluster with video and graphics accelerators
this patch add the basic support for i.MX8MM.
