The index of lbr_sel_map is bit value of perf branch_sample_type.
PERF_SAMPLE_BRANCH_MAX is 1024 at present, so each lbr_sel_map uses
4096 bytes. By using bit shift as index, we can reduce lbr_sel_map
size to 40 bytes.

Currently uprobes don't pass is_return to the argument parser so that
it cannot make use of "$retval" fetch method since it only works for
return probes.

Use separate method to fetch from memory. Move existing functions to
trace_kprobe.c and make them static. Also add new memory fetch
implementation for uprobes.

Fetching from user space should be done in a non-atomic context. So
use a per-cpu buffer and copy its content to the ring buffer
atomically. Note that we can migrate during accessing user memory
thus use a per-cpu mutex to protect concurrent accesses.

The deref fetch methods access a memory region but it assumes that
it's a kernel memory since uprobes does not support them.

differently later.

Added Merrifield watchdog driver support.
Based on initial implementation from prior Intel SCU-based platforms, this
driver has several changes specific to the Tangier SoC / Merrifield platform.
