If mapping the CvP BAR fails, we still can configure the FPGA via
PCI config space access. In this case the iomap pointer is NULL.
On x86_64, passing NULL address to pci_iounmap() generates
"Bad IO access at port 0x0" output with stack call trace. Fix it.

The patch fixes:
hv_kvp_daemon.c: In function 'kvp_set_ip_info':
hv_kvp_daemon.c:1305:2: note: 'snprintf' output between 41 and 4136 bytes
into a destination of size 4096
The "(unsigned int)str_len" is to avoid:
hv_kvp_daemon.c:1309:30: warning: comparison of integer expressions of
different signedness: 'int' and 'long unsigned int' [-Wsign-compare]

Currently we are replicating state in struct hv_context that is unnecessary -
this state can be retrieved from the hypervisor. Furthermore, this is a per-cpu
state that is being maintained as a global state in struct hv_context.
Get rid of this state in struct hv_context.

By default, when ACPI tables and FDT coexist for ARM64,
current kernel takes precedence over FDT to get device information.
Virt machine in qemu provides both FDT and ACPI table. Increases the
way to get information through FDT.

The notify set operation ioctl will wait till timeout is expired
even in case when the FW returned an error.
Check the status field of the client object in wait_event_timeout()
to determine if the caller can return earlier.

During queues flush, the me client in most cases is already
unlinked hence the me client id is unavailable. The host client
structure pointer is enough for identification.
The function mei_cl_cmp_id() is dropped as it has no more usage.

Drop BUG() from the hbm handler in order not to crash the whole
kernel on faulty firmware implementation. Instead of it, just return
an error resulting into link reset.
There is no any known issue of faulty firmware in this matter,
the change is just to ease the development.
