This adds support for the PMIC wrapper found on MediaTek MT8135 and
MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these
are currently not supported.

On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via
SPI. The SPI master interface is not directly visible to the CPU, but
only through the PMIC wrapper inside the SoC. The communication between
the SoC and the PMIC can optionally be encrypted. Also a non standard
Dual IO SPI mode can be used to increase speed. The MT8135 also supports
a special feature named "IP Pairing". With IP Pairing the pins of some
SoC internal peripherals can be on the PMIC. The signals of these pins
are routed over the SPI bus using the pwrap bridge. Because of these
optional non SPI conform features the PMIC driver is not implemented as
a SPI bus master driver.

We mask the event with the CCI_PMU_EVENT_MASK, before passing
the config to pmu_validate_hw_event(), which causes extra bits
to be ignored and qualifies an invalid event code as valid.

e.g,
 $ perf stat -a -C 0 -e CCI_400/config=0x1ff,name=cycles/ sleep 1
   Performance counter stats for 'system wide':

         506951142      cycles

       1.013879626 seconds time elapsed

where, cycles has an event coding of 0xff. This patch also removes
the unnecessary 'event' mask in pmu_write_register, since the config_base
is set by the pmu code after the event is validated.

Avoid secure transactions while probing the CCI PMU. The
existing code makes use of the Peripheral ID2 (PID2) register
to determine the revision of the CCI400, which requires a
secure transaction. This puts a limitation on the usage of the
driver on systems running non-secure Linux(e.g, ARM64).

Updated the device-tree binding for cci pmu node to add the explicit
revision number for the compatible field.

The supported strings are :
	arm,cci-400-pmu,r0
	arm,cci-400-pmu,r1
	arm,cci-400-pmu - DEPRECATED. See NOTE below

NOTE: If the revision is not mentioned, we need to probe the cci revision,
which could be fatal on a platform running non-secure. We need a reliable way
to know if we can poke the CCI registers at runtime on ARM32. We depend on
'mcpm_is_available()' when it is available. mcpm_is_available() returns true
only when there is a registered driver for mcpm. Otherwise, we assume that we
don't have secure access, and skips probing the revision number(ARM64 case).

The MCPM should figure out if it is safe to access the CCI. Unfortunately
there isn't a reliable way to indicate the same via dtb. This patch doesn't
address/change the current situation. It only deals with the CCI-PMU, leaving
the assumptions about the secure access as it has been, prior to this patch.

CCI400 has different event specifications for PMU, for revsion
0 and revision 1. As of now, we check the revision every single
time before using the parameters for the PMU. This patch abstracts
the details of the pmu models in a struct (cci_pmu_model) and
stores the information in cci_pmu at initialisation time, avoiding
multiple probe operations.

The perf core implicitly rejects events spanning multiple HW PMUs, as in
these cases the event->ctx will differ. However this validation is
performed after pmu::event_init() is called in perf_init_event(), and
thus pmu::event_init() may be called with a group leader from a
different HW PMU.

The CCI PMU driver does not take this fact into account, and assumes
that the any other hardware event belongs to the CCI. There are two
issues with it :

1) It is wrong and we should reject such groups.
2) Validation allocates an temporary idx for this non-cci event, which leads
to wrong calculation of the counter availability, and eventually lesser
number of events in the group.

This patch updates the CCI PMU driver to first test for and reject
events from other PMUs, which is the right thing to do.
