The driver uses irq_set_affinity_hint() to:
- Set the affinity_hint which is consumed by the userspace for
distributing the interrupts
- Enforce affinity
As per commit 6ac17fe8c14a ("mailbox: bcm-flexrm-mailbox: Set IRQ affinity
hint for FlexRM ring IRQs") the latter is done to ensure that the FlexRM
ring interrupts are evenly spread across all available CPUs. However, since
commit a0c9259dc4e1 ("irq/matrix: Spread interrupts on allocation") the
spreading of interrupts is dynamically performed at the time of allocation.
Hence, there is no need for the drivers to enforce their own affinity for
the spreading of interrupts.
Also, irq_set_affinity_hint() applying the provided cpumask as an affinity
for the interrupt is an undocumented side effect. To remove this side
effect irq_set_affinity_hint() has been marked as deprecated and new
interfaces have been introduced. Hence, replace the irq_set_affinity_hint()
with the new interface irq_update_affinity_hint() that only sets the
affinity_hint pointer.

Like i.MX8 SCU, i.MX8ULP S4 also has vendor specific protocol.
- bind SCU/S4 MU part to share one tx/rx/init API to make code simple.
- S4 msg max size is very large, so alloc the space at driver probe,
not use local on stack variable.
- S4 MU has 8 TR and 4 RR which is different with i.MX8 MU, so adapt
code to reflect this.

driver, let us use the same to save the channel specific information
in it so that we can it whenever required instead of parsing the PCCT
table entries every time in both pcc_send_data and pcc_mbox_irq.

Extended PCC subspaces introduces more registers into the PCCT. In order
to consolidate access to these registers and to keep all the details
contained in one place, let us introduce PCC register bundle that holds
the ACPI Generic Address Structure as well as the virtual address for
the same if it is mapped in the OS.
It also contains the various masks used to access the register and
the associated read, write and read-modify-write accessors.
We can also clean up the initialisations by having a helper function

Now that we have all the shared memory region information populated in
the pcc_mbox_chan, let us propagate the pointer to the same as the
return value to pcc_mbox_request channel.
This eliminates the need for the individual users of PCC mailbox to
parse the PCCT subspace entries and fetch the shmem information. This
also eliminates the need for PCC mailbox controller to set con_priv to
PCCT subspace entries. This is required as con_priv is private to the
controller driver to attach private data associated with the channel and
not meant to be used by the mailbox client/users.
Let us convert all the users of pcc_mbox_{request,free}_channel to use
new interface.

Currently PCC mailbox controller sets con_priv in each channel to hold
the pointer to pcct subspace entry it corresponds to. The mailbox user
will then fetch this pointer from the channel descriptor they get when
they request for the channel. Using that pointer they then parse the
pcct entry again to fetch all the information about shared memory region.
In order to remove individual users of PCC mailbox parsing the PCCT
subspace entries to fetch same information, let us consolidate the same
in pcc mailbox controller by parsing all the shared memory region
information into a structure that can also hold the mbox_chan pointer it
represent.
This can then be used as main PCC mailbox channel pointer that we can
return as part of pcc_mbox_request_channel instead of standard mailbox
channel pointer.

Extended PCC subspaces(Type 3 and 4) differ from generic(Type 0) and
HW-Reduced Communication(Type 1 and 2) subspace structures. However some
fields share same offsets and same type of structure can be use to
extract the fields. In order to simplify that, let us move all the doorbell
register parsing into pcc_parse_subspace_db_reg and consolidate there.
It will be easier to extend it if required within the same.

Currently all the PCC channel specific information are stored/maintained
in global individual arrays for each of those information. It is not
scalable and not clean if we have to stash more channel specific
information. Couple of reasons to stash more information are to extend
the support to Type 3/4 PCCT subspace and also to avoid accessing the
PCCT table entries themselves each time we need the information.
This patch moves all those PCC channel specific information into a
separate structure pcc_chan_info.
