GENI serial engine driver provides common functionality used by
other serial bus drivers (such as I2c, SPI, UART), and does
resource management for those drivers. Add ICC API support also.

Add error messages into the regulator_check_voltage() and
regulator_check_consumers() functions which explain exactly what
is not correct about given voltage requests. This makes
debugging regulator_set_voltage() errors easier.

The important part of qrtr_port_lookup() wrt synchronization is that the
function returns a reference counted struct qrtr_sock, or fail.
As such we need only to ensure that an decrement of the object's
refcount happens inbetween the finding of the object in the idr and
qrtr_port_lookup()'s own increment of the object.
By using RCU and putting a synchronization point after we remove the
mapping from the idr, but before it can be released we achieve this -
with the benefit of not having to hold the mutex in qrtr_port_lookup().

In order to prevent overconsumption of resources on the remote side QRTR
implements a flow control mechanism.
The mechanism works by the sender keeping track of the number of
outstanding unconfirmed messages that has been transmitted to a
particular node/port pair.
Upon count reaching a low watermark (L) the confirm_rx bit is set in the
outgoing message and when the count reaching a high watermark (H)
transmission will be blocked upon the reception of a resume_tx message
from the remote, that resets the counter to 0.
This guarantees that there will be at most 2H - L messages in flight.
Values chosen for L and H are 5 and 10 respectively.

The confirm-rx bit is used to implement a per port flow control, in
order to make sure that no messages are dropped due to resource
exhaustion. Move the resume-tx transmission to recvmsg to only confirm
messages as they are consumed by the application.

As the endpoint is unregistered there might still be work pending to
handle incoming messages, which will result in a use after free
scenario. The plan is to remove the rx_worker, but until then (and for
stable@) ensure that the work is stopped before the node is freed.

This snapshot is taken as of msm-4.19 'commit <d2f41beab007i>
("Merge "msm: npu: Add bandwidth monitor support"")'.
This change brings the rpmsg and rpmsg glink drivers up to date with
the fixes from msm-4.19. In addition, change the copyrights to SPDX format.
Also, irq_set_affinity and sched_setaffinity can not be used when compiling
a driver as a module. Hence, moving to module-friendly APIs.
