Add mt8195 support.

Support comes directly from commit e88edc977b00 ("soc: mediatek: pwrap:
add pwrap driver for MT8195 SoC") from the Linux Kernel.

to be consistent with other definitions.

Change the logic for selecting pmic_children_info to use the compatible
string from the devicetree instead of expecting the pwrap (part of the
MCU) to correspond to the separate PMIC chip.

In addition to being more correct, it also saves a few lines of code for
each MCU type that is added by dropping the enum and type field.

Remove the interrupt related code in mtk-pwrap driver. This was just
enabling interrupts without any handler.

Even if we did have a handler, the only thing we could do is log a
message. Since U-Boot isn't long running, this likely wouldn't be very
useful.

Drop the PWRAP_SLV_CAP_DUALIO flag from the mt6359 PMIC definition. The
mt6359p variant of the PMIC does support dual I/O.

Prior to this change, the driver would attempt to write to the
PWRAP_DEW_DIO_EN register, which was not defined, so would write
register 0 (DONE2).

Add a PWRAP_CAP_INIT capability flag to specify if it is safe to call
pwrap_init() or not. Not all targets define the registers accessed
by pwrap_init(). In that case, it is expected that an earlier bootloader
has already initialized the PMIC. If not, we now return an error instead
of trying to access undefined registers.

Add a PWRAP_CAP_WDT_SRC flag to indicate if a PMIC wrapper has a WDT_SRC
or not. Then use this to conditionally enable the watchdog timer.

Prior to this change, since the register was not defined, it defaulted
to 0, so the wrong register (DONE2) was being written to.

Fix the comment at the start of the file to accurately describe what
this file does. The old description was likely copied from the related
regulator driver.

As exposed by "make randconfig", we have an issue around how
SYSRESET_CMD_POWEROFF is typically selected. We cannot rely only on
CMD_POWEROFF as SYSRESET_CMD_POWEROFF must also be tested for its own
dependency of SYSRESET.

Add a condition to enable the PMIC sysreset function via the
system-power-controller device tree property in addition to the existing
Kconfig dependency, provided the PMIC supports it.
