Add driver for Microchip PolarFire SoC (MPFS) peripheral clock and soft
reset control.
Normally, the peripheral clocks and reset state are controlled by the
Hart Software Services (HSS) running on the Monitor processor. As an
alternative to using HSS services, applications can now enable the reset
controller in a device tree overly, for example:
&reset {
status = "okay";
};
&uart4 {
resets = <&reset MSS_RESET_ID_MMUART4>;
};
Embedded the reset controller node in system controller node.

The CH32V003 has a 8 channel, 10 bit onboard ADC. Add an immediate
mode driver and the appropriate pinctrl bindings. Note that the
CH32V003 GPIO pins have both a floating input and an analogue input
mode, and the pinctrl is needed to put the pin in analogue mode.

The WCH External Trigger and Interrupt controller (EXTI) supports
between 8 and 22 lines where each line can trigger an interrupt on
rising edge, falling edge, or both edges. Lines are assigned to a
group, and each group has a separate interrupt. On the CH32V003/6,
there is one group of 8 lines, while on the CH32V208 there are
multiple groups with between one and six lines per group.
In the same way as the STM32 and GD32, define an EXTI driver that
configures the peripheral and an internal interface that can configure
individual lines.

The CH32V20x and CH32V30x SoCs have 16 pins per GPIO bank, but in the
devicetree, `ngpios` was incorrectly set to 8.
Fix the devicetrees by setting the correct value.

This enables the clock_control driver build on bl60x.
It is currently deferred init, due to being incompatible
with current SDK-based boot, to avoid later giant PR.

Timer 7 is not used in timer driver, which means that timer
driver doesn't initialize timer 7, it's just declared in dtsi.
So I remove it, timer 7 will be used as alarm timer for counter driver.

Current ESP32 clock system is mixed with RTC labeling/registers,
but it doesn't implement a real-time clock (RTC) driver.
To avoid confusion and allow adding a proper RTC driver later,
this commit renames the existing RTC interface to CLOCK and make
it as a subsystem without any peripheral attached to it.
This better reflects its actual purpose as a general clock controller.

Commit 42fb9067e4 makes it mandatory to

This commit updates all relevant device tree source files using the
riscv,machine-timer binding to explicitly define `reg-names` for the MTIME
and MTIMECMP registers.
This change ensures compatibility with the updated riscv_machine_timer
driver, which now relies on `reg-names` to resolve register addresses
instead of using fixed index positions.

The CH32V006 is part of the CH32V00x series of 32 bit RISC-V
microcontrollers. This series is an evolution of the CH32V003 which
was used as a basis for this Devicetree definition.
Compared to the CH32V003, thie CH32V006 has an extra GPIO port (PB),
an extra UART (UART2), 8 KiB of RAM, 62 KiB of flash, and uses the
QingKe V2C core.

The GPTM is a general purpose module with a 16 bit prescaler, 16 bit
