Add a Kconfig option, similar to the one that is already available
for nRF5340, that allows enabling the REG0 (VDDH) DC/DC converter
in nRF52840. Make use of this option in Nordic boards: nRF52840 DK
and nRF52840 Dongle.

GPIO L/K groups:
On IT81202 (128-pins package), the pins of GPIO group K and L aren't
bonding with pad. So we configure these pins as internal pull-down
at default to prevent leakage current due to floating.
GPIOH7:
On IT81202/IT81302, the GPIOH7 isn't bonding with pad and is left
floating internally. We need to enable internal pull-down for the pin
to prevent leakage current, but IT81202/IT81302 doesn't have the
capability to pull it down. We can only set it as output low,
so we enable output low for it at initialization to prevent leakage.
After setting: power saving=2.26mA

Code removed:
- IT8XXX2 doesn't support soc level software interrupt hence remove
them.
- To use common macro to access csr (control status register).
- To remove CONFIG_RISCV_HAS_PLIC related code. IT8XXX2 uses its own
interrupt controller code.
- To remove ite_write and ite_read. We don't use them anymore.
Code changed:
- Return true from arch_irq_is_enabled() when external interrupt-enable

Fixes: #38591, #38207, #37861
The commit 65a2de84a9 aligned the data
linker symbol for sections and regions.
The data region symbol start has been placed outside the sections thus
being defined as the address of the region before alignment of the first
section in the data region, usually the `datas` section.
The symbol defining the start address of the data section is after
section alignment.
In most cases the address of the data region start and datas section
start will be identical, but not always.
The data region symbol is a new linker symbol and existing code has
been depending on the old data section start symbol.
Thus, the update to the use of the data region start symbol instead of
data ram start symbol thus results in a different address when the
section is aligned to a different address.
To ensure the original behavior in all cases, the data region start
address is now moved inside the data section.

Following the migration of the clock source configuration in DTS (commit
2691541ad2), HSI is always used as wake-up source on STM32LX. It is
reconfigured as MSI just after, but it slightly increase the wake-up
time and power consumption.
It happens as the file defining STM32_SYSCLK_SRC_MSI is not included.

It happens that CM7 wakeups CM4, before CM4 goes to sleep.
Thus when CM4 goes to sleep,
there no more wakeup from CM7. And CM4 hangs.
For a simple synchronisation implementation,
CM4 doesn't go to sleep any more,
instead it waits (active wait) for CM7 to take HSEM
(meaning that clock configuration is finished).

Call __reset instead of directly calling __initialize from the common
RISC-V privileged SoC vectors __start. This allows injection of SoC
specific reset code just after setting up the machine trap vector.

calls __initialize.
