Convert the board to use DM_PMIC instead of the legacy SPL I2C/PMIC
handling.

Changes include:
- Enable DM_PMIC, DM_PMIC_PCA9450, and SPL_DM_PMIC_PCA9450 in defconfig.
- Drop legacy SPL I2C and PMIC options.
- Remove manual I2C1 pad setup and legacy power_pca9450_init() usage.
- Use DM-based pmic_get() with the DT node "pmic@25".
- Update PMIC register programming to use struct udevice API.

As explained in commit 03d2d5fc003f ("board: sifive: unmatched: set
fdtfile with unquoted variable.") using the syntax of
'fdtfile=CONFIG_DEFAULT_FDT_FILE' in the plain text environment files
will lead to extraneous and problematic "s in the output. This is fixed
by using fdtfile=DEFAULT_FDT_FILE which was introduced recently.

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

We want to change the bootdevice dynamically, so that when booting
U-Boot from sdcard, kernel is also preferably booted from sdcard by
default. If the user decides to set their own bootorder, this should not
be overwritten. This was already implemented for imx8mp-libra-fpsc
board, but as we set the default value for boot_targets in devicetree
now, the env_get_default will return NULL. Also env_get might return
NULL when boot_targets is not set. A string compare with NULL is unsafe
and should be avoided. To fix this we only change the env value if the
variable was not set before (NULL), as this is the new default value.
In any other case the user has changed the value so it will not be
overwritten.
Also let standardboot set bootcmd automatically. For this
CONFIG_USE_BOOTCOMMAND needs to be activated.

Standardboot allows setting bootdevices and bootmeths in devicetree.
This is already implemented for imx8mp-libra board.

Add emmc_dev and sd_dev env variables with comment that they are needed
for builtin uuu flash scripts. This is already done for imx8mp-libra
board.

Netboot script is named net_boot_fit.scr.uimg with ampliphy-boot.
fit_fdtconf is not longer needed. The default config is automatically
fetched from the fitImage. mmcroot is also not longer used, the
bootscript has a builtin default. bootenv_addr_r is no longer used, as
the bootenv is loaded into loadaddr.

Add rauc to bootmeths variable if BOOTMETH_RAUC is enabled. This is
setting a proper default for RAUC enabled systems.
