Accumulated patchsets for bsp/cvitek (#8968)

* bsp: cvitek: kconfig: add wdt for cv18xx_riscv

Add Watchdog timer in Kconfig.

Signed-off-by: Chen Wang <[email protected]>

* drv: cvitek: remove using macro from source file

Building of source file should be controlled by SConscript,
but not in source file itself.

* bsp: cvitek: kconfig: add i2c for cv18xx_riscv

Add I2C in Kconfig for c906B.

Note, the IRQ# is different from that of c906L.

* bsp: cvitek: kconfig: add rtc for cv18xx_riscv

Add RTC in Kconfig for c906B.

* bsp: cvitek: fix channel issue for pwm driver

The original code confuses the concepts of controllers and channels.
Fixed it and do some code cleanup.

* bsp:cvitek: add i2c pinmux config for cv18xx_riscv

Pinmux in driver code is controlled by SOC type, bcos driver
code should be general and support all pins defined by SoC.

Pinmux configuration in Kconfig is controlled by BOARD type,
bcos when we operate on board, it does not expose all chip-level
pin signals and we can only use part of them.

Following is I2C signals exported by duo family. Details see
https://milkv.io/docs/duo/overview.

Note: we have not added support for duo-S.
