Use IRQF_NO_SUSPEND flag instead of enable_irq_wake to
support interrupt wake up from suspend.

Since hardware is supporting multiple IPCC instance,
use ipcc_%d instead of ipcc as the irq name to support
in driver.

Dynamic alloc for channel arrangement instead of static alloced
array, it is more flexible and can reduce memory usage.

mailbox: qcom-ipcc: Enable loading QCOM_IPCC as a module2021-08-30T04:50:15ZAmit Pundir2021-07-16T07:49:46Zurn:sha1:8d7e5908c0bcf8a0abc437385e58e49abab11a93
This patch enables the qcom_ipcc driver to be loaded as a
module. IPCC is fairly core to system, so as such it should
never be unloaded. It registers as a mailbox + irq controller
and the irq controller drivers in kernel are not supposed to
be unloaded as they don't have the visibility over the clients
consuming the irqs. Hence adding supress_bind_attrs to disable
bind/unbind via sysfs.

Fix IPCC (Inter-Processor Communication Controller) channel exhaustion by
setting the channel private data to NULL on mbox shutdown.

mailbox: Add support for Qualcomm IPCC2020-05-30T23:43:23ZManivannan Sadhasivam2020-05-30T23:15:12Zurn:sha1:fa74a0257f45c5a92b82ae95c8455f06c598792f
Add support for the Inter-Processor Communication Controller (IPCC)
block from Qualcomm that coordinates the interrupts (inbound & outbound)
for Multiprocessor (MPROC), COMPUTE-Level0 (COMPUTE-L0) & COMPUTE-Level1
(COMPUTE-L1) protocols for the Application Processor Subsystem (APSS).
This driver is modeled as an irqchip+mailbox driver. The irqchip part
helps in receiving the interrupts from the IPCC clients such as modems,
DSPs, PCI-E etc... and forwards them to respective entities in APSS.
On the other hand, the mailbox part is used to send interrupts to the IPCC
clients from the entities of APSS.
