soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver

The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
Hardware module used to collect all the requests from both software and the
various remote processors embedded into the SoC and decide about a minimum
operating voltage and a minimum DRAM frequency to fulfill those requests in
an effort to provide the best achievable performance per watt.

This hardware IP is capable of transparently performing direct register R/W
on all of the DVFSRC-controlled regulators and SoC bandwidth knobs.

This driver includes support for MT8183, MT8192 and MT8195.

With the following configuration options:

drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]

Looking at the code, both drivers can only bind to OF-defined device
nodes, so these drivers are useless without OF and should therefore
depend on it.

Also drop of_match_ptr() from both drivers. We already know what it
will resolve to, so we might as well save cpp some work.

Developers or QA teams who wish to test-build the code can still do
so by enabling CONFIG_OF, which is available on all architectures and
has no dependencies.

The mmsys driver supports only MT8173 device for now, but like other system

it depends on the mt8173 clock specific driver but that dependency is
not real as it can build without the clock driver. Instead of depends on
a specific model, make the driver depends on the generic ARCH_MEDIATEK and
enable by default so other Mediatek devices can start using it without

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.
