privileged instruction set SoC support.
This allows overriding soc_interrupt_init for SoCs which are not fully

esp32c3 has already supported RISC-V GP, just apply new kconfig option
to it. Forcely select CONFIG_RISCV_GP in esp32c3 at first because it
seems to be necessary in the esp32c3 SoC.

Initialize GP at common entry point of riscv-privilege SoCs so that
this commit add GP support of these SoCs at once.
As some privilege SoCs want to customize the entry point, they should
disable linker relaxation by `.norelax option` before entrying the
common entry point `__start`.

This reverts commit 7b09d031fa. Because
context save of GP register is removed, we don't need to initialize GP
at thread init. GP will be a constant value so that it could only be
initialized at program start.

Current location options for linker source files includes init and
noinit ram data, but only a noinit ram section. This makes it impossible
for application code to define an initialized RAM output section,
such as with the Z_ITERABLE_SECTION_RAM() helpers.
Adding a DATA_SECTIONS linker source option for this use case.

rv32m1_vega don't boot due to device init ordering and changes with the
device model. The soc code is looking for a device pointer for the
intmux. Change to using DEVICE_DT_GET here as that will ensure we get
a valid pointer and by the time we need to utilize the pointer the
intmux driver will have been initialized and thus the device pointer
will be ready.
Also set BUILD_OUTPUT_HEX since we utilize openocd to flash and west
flash is looking for a hex file for openocd targets.
