Add 'save_context' ops to save register value of clock and
'restore_context' ops to restore the value to register.
The ops only suitable for SYS, AON and STG clock tree not ISP and VOUT.

The implementation assumes that exactly the same kernel is booted on the
same hardware.
We save the build number and date to the swap header so that we guarantee
not to resume with a different kernel upon booted up the hibernated image.
swsusp_arch_resume() and swsusp_arch_suspend() are coded as dummy
functions for now and shall complete in the subsequent patches.

The SBI PMU platform driver did not provide any identification for
perf events matching. This patch introduces a new sysfs file inside the
platform device (soc:pmu/id) for pmu identification.
The identification is a 64-bit value generated as:
[63-32]: mvendorid;
[31]: marchid[MSB];
[30-16]: marchid[15-0];
[15-0]: mimpid[15MSBs];
The CSRs are detailed in the RISC-V privileged spec [1].
The marchid is split in MSB + 15LSBs, due to the MSB being used for
open-source architecture identification.

The existing pmu documentation describes the limitation of perf
infrastructure in RISC-V ISA and limited feature set of perf in RISC-V.
However, SBI PMU extension and sscofpmf extension(ISA extension) allows to
implement most of the required features of perf. Remove the old
documentation which is not accurate anymore.

The sscofpmf extension allows counter overflow and filtering for
programmable counters. Enable the perf driver to handle the overflow
interrupt. The overflow interrupt is a hart local interrupt.
Thus, per cpu overflow interrupts are setup as a child under the root
INTC irq domain.

Currently, the /proc/cpuinfo outputs the entire riscv,isa string which
is not ideal when we have multiple ISA extensions present in the ISA
string. Some of them may not be enabled in kernel as well.
Parse only the enabled ISA extension and print them in a separate row.

The isa string should begin with either rv64 or rv32. Otherwise, it is
an incorrect isa string. Currently, the string parsing continues even if
it doesnot begin with current XLEN.
Fix this by checking if it found "rv64" or "rv32" in the beginning.

Current hart ISA ("riscv,isa") parser don't correctly parse:
1. Multi-letter extensions
2. Version numbers
All ISA extensions ratified recently has multi-letter extensions
(except 'H'). The current "riscv,isa" parser that is easily confused
by multi-letter extensions and "p" in version numbers can be a huge
problem for adding new extensions through the device tree.
Leaving it would create incompatible hacks and would make "riscv,isa"
value unreliable.
This commit implements minimal parser for "riscv,isa" strings. With this,
we can safely ignore multi-letter extensions and version numbers.

This commit replaces BITS_PER_LONG with number of alphabet letters.
Current ISA pretty-printing code expects extension 'a' (bit 0) through
'z' (bit 25). Although bit 26 and higher is not currently used (thus never
cause an issue in practice), it will be an annoying problem if we start to
use those in the future.
This commit disables printing high bits for now.

RISC-V SBI specification added a PMU extension that allows to configure
start/stop any pmu counter. The RISC-V perf can use most of the generic
perf features except interrupt overflow and event filtering based on
privilege mode which will be added in future.
It also allows to monitor a handful of firmware counters that can provide
insights into firmware activity during a performance analysis.
