- Add base addresses for WDG3, WDG4, GPIO6, and GPIO7 for i.MX94.
- Introduce common.h with macros of clock IDs, power domains, and CPU
  types for platform-specific replacement (e.g., i.MX94, i.MX95).
- Extend imx_get_mac_from_fuse() to support i.MX94.

System Manager provides the last booted and shutdown reasons of the
logical machines (LM) and system using the SCMI misc protocol (Protocol
ID: 0x84, Message ID: 0xA). This path adds get_reset_reason() to query
and print these reasons in SPL and U-Boot.

The LPCG number on iMX93 and iMX91 is 127 not 122. The wrong
value is used in ccm_reg structure and Coverity reports several
issues as out-of-bounds write.

Reuse and export low_drive_freq_update() function. This way global imx9
board_fix_fdt() doesn't duplicate code. While low_drive_freq_update()
can be reused on boards such as phyCORE-i.MX93 (TARGET_PHYCORE_IMX93)
which is not using the global imx9 board_fix_fdt() implementation.

While at it, make printout logic less verbose by only outputting on the
error condition and not on each successful clock fixup. Also drop now
invalid comment (low_drive_freq_update() now does fixup for internal and
kernel device-tree).

Add the initial board support for the NXP i.MX93 FRDM board:

https://www.nxp.com/design/design-center/development-boards-and-designs/frdm-i-mx-93-development-board:FRDM-IMX93

Based on the NXP U-Boot code.

There were attempts to upstream the board devicetree, but it has not been
accepted upstream yet:

https://lore.kernel.org/linux-arm-kernel/20250526-fpg-nxp-imx93-frdm-v2-2-e5ad0efaec33@pengutronix.de/

Once it reaches upstream, we can switch to OF_UPSTREAM.

This patch adds i.MX95 SoC and clock related code. Because they are
based on SCMI, put them in the scmi subfolder.

Drop global ddrphy_trained_csr which maybe different with per board
ddrphy_trained_csr. DDR TOOL generates ddrphy_trained_csr for each
board, using the global ddrphy_trained_csr has risk that values may
be not up to date.
