Switch the entire clk-imx6q driver to clk_hw based API.
Add imx6q_obtain_fixed_clk_hw helper to clean up the registration

This is documented in the reference manuals as GIC_CLK_ROOT.
In some out-of-tree DVFS scenarios the gic clock can end up as the only
user of sys_pll2 so if we don't define the gic clk explicitly it might
be turned off.
This applies to both 8mq and 8mm: same clk register but diffferent
parents.

Pull perf tooling updates from Ingo Molnar:
"perf.data:
- Streaming compression of perf ring buffer into
PERF_RECORD_COMPRESSED user space records, resulting in ~3-5x
perf.data file size reduction on variety of tested workloads what
saves storage space on larger server systems where perf.data size
can easily reach several tens or even hundreds of GiBs, especially
when profiling with DWARF-based stacks and tracing of context
switches.
perf record:
- Improve -user-regs/intr-regs suggestions to overcome errors
perf annotate:
- Remove hist__account_cycles() from callback, speeding up branch
processing (perf record -b)
perf stat:
- Add a 'percore' event qualifier, e.g.: -e
cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
both hardware threads in a core.
We can already do this with --per-core, but it's often useful to do
this together with other metrics that are collected per hardware
thread.
I.e. now its possible to do this per-event, and have it mixed with
other events not aggregated by core.
arm64:
- Map Brahma-B53 CPUID to cortex-a53 events.
- Add Cortex-A57 and Cortex-A72 events.

- Add DWARF register mappings for libdw, allowing --call-graph=dwarf
to work on the C-SKY arch.

- Add support for recording and printing XMM registers, available,
for instance, on Icelake.
- Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
support. UPI replaced the Intel QuickPath Interconnect (QPI) in
Xeon Skylake-SP.

- Fix instructions sampling rate.

Pull RISC-V updates from Palmer Dabbelt:
"This contains an assortment of RISC-V related patches that I'd like to
target for the 5.2 merge window. Most of the patches are cleanups, but
there are a handful of user-visible changes:
- The nosmp and nr_cpus command-line arguments are now supported,
which work like normal.
- The SBI console no longer installs itself as a preferred console,
we rely on standard mechanisms (/chosen, command-line, hueristics)
instead.
- sfence_remove_sfence_vma{,_asid} now pass their arguments along to
the SBI call.
- Modules now support BUG().
- A missing sfence.vma during boot has been added. This bug only
manifests during boot.
- The arch/riscv support for SiFive's L2 cache controller has been
merged, which should un-block the EDAC framework work.
I've only tested this on QEMU again, as I didn't have time to get
things running on the Unleashed. The latest master from this morning
merges in cleanly and passes the tests as well"

'ifeq ... else ifneq ... endif' notation is supported by GNU Make 3.81
or later, which is the requirement for building the kernel since
commit 37d69ee30808 ("docs: bump minimal GNU Make version to 3.81").
Use it to improve the readability.

Currently on panic, kernel will lower the loglevel and print out pending
printk msg only with console_flush_on_panic().
Add an option for users to configure the "panic_print" to replay all
dmesg in buffer, some of which they may have never seen due to the
loglevel setting, which will help panic debugging .
