Subject: [PATCH v2 0/3] support for Amlogic SPI Flash Controller IP

This Flash Controller is derived by adding an SPI path to the original
raw NAND controller. This controller supports two modes: raw mode and
SPI mode. The raw mode has already been implemented in the community
(drivers/mtd/nand/raw/meson_nand.c).
This submission supports the SPI mode.

Add the drivers and bindings corresponding to the SPI Flash Controller.

Changes in v2:
- Remove clock reg descriptor and get clock from common clk.
- Remove ecc and ramdom descriptor in bindings.
- Modify the format and message description.
- Link to v1: https://lore.kernel.org/r/20250808-spifc-v1-0-ff4e30e26a6b@amlogic.com
