msm: implement ARCH_RANDOM

Currently, the software random number generator is not intialized
until relatively late in the boot process. Software that relies on
random numbers early will not be reliable. Entropy sources are
available early but not early enough for some use cases which means
that moving the software random number generation earlier is not an
option. As an alternate solution, implement the functions associated
with CONFIG_ARCH_RANDOM. These functions currently make a call into
trustzone to get reliable random numbers. The functions are disabled
once the regular random number generator is sufficiently reliable.

ARM: hw_breakpoint: enable HAVE_HW_BREAKPOINT feature flag

HAVE_HW_BREAKPOINT was disabled temporarily from commit
480a82f59712136b51ee5ca05c4f22c1738010c5. Issue not seen with the
latest kernel hence re-enable the feature and fix merge issue from
previous kernel upgrade.

scripts/kallsyms: filter symbols not in kernel address space

This patch uses CONFIG_PAGE_OFFSET to filter symbols which
are not in kernel address space because these symbols are
generally for generating code purpose and can't be run at
kernel mode, so we needn't keep them in /proc/kallsyms.

For example, on ARM there are some symbols which may be
linked in relocatable code section, then perf can't parse
symbols any more from /proc/kallsyms, this patch fixes the
problem (introduced b9b32bf70f2fb710b07c94e13afbc729afe221da)
