Enable multiple DTB support in the FIT image for the Spacemit K1 SoC,
allowing a single U-Boot binary to support different board variants.
The SPL reads the board type from EEPROM and selects the corresponding
device tree at runtime via board_fit_config_name_match(), ensuring the
correct hardware description is passed to U-Boot proper.

Add nor_early_init() to probe the QSPI controller and SPI NOR flash
in SPL. Switch spl_boot_device() to BOOT_DEVICE_SPI so the board
boots from SPI flash.
Change the default device tree to k1-musepi-pro, whose u-boot
overlay already defines the QSPI controller and flash node with
bootph-pre-ram markers. Enable the required SPI driver model and
flash config options.

Add Spacemit P1 SoC support in SPL. And set the default voltage
for BUCKs and LDOs.
Also update MAINTAINERS: add Guodong Xu as co-maintainer, list the
u-boot-spacemit mailing list, register the new K1 driver files (i2c,
PMIC, regulator), and fix a pre-existing '@@' typo in Huan Zhou's
email.

Include DDR initialization firmware in the SPL image. The firmware
path can be specified via the DDR_FW_FILE environment variable. If
the firmware is not found, an empty placeholder file is created to
allow the build to proceed without DDR initialization support.

Initialize clock and serial devices in SPL. Otherwise, the device
driver won't be loaded in SPL.
