Wire board/nxp/common/vid.c into the <pmbus.h> framework so the legacy
NXP AVS path stops carrying its own duplicate copy of the PMBus
protocol and instead consumes the shared constants, decoders, and
transport helpers.
vid.c is the legacy NXP AVS/pre-kernel voltage-trim path for lx2160 CPUs.
It does PMBus to whichever core-rail voltage monitor the board carries:
LTC3882 or ISL68233 are selected with
CONFIG_VOL_MONITOR_LTC3882_*/CONFIG_VOL_MONITOR_ISL68233_*.
Before this change the file kept its own local PMBUS_CMD_* command-code
defines, its own inline LINEAR16 mantissa/exponent math, and called
into I2C through the I2C_READ/I2C_WRITE NXP wrappers in
board/nxp/common/i2c_common.{c,h} which is a parallel implementation of
exactly what <pmbus.h> + lib/pmbus.c provides.
The intent is to make vid.c an consumer of the new PMBus.
Compatibility with the former support:
- CLI unchanged: vdd_override and vdd_read keep their existing
semantics, return codes, and diagnostic output.
- I2C transport unchanged on the wire: the framework's pmbus_*
helpers call dm_i2c_read/dm_i2c_write: the same DM I2C
backing that vid.c's former I2C_READ/I2C_WRITE macros already
routed through on DM_I2C.
- Numeric decode is bit-equivalent: pmbus_reg2data_linear16() and
pmbus_data2reg_linear16() implement the PMBus 1.3 Part II
mantissa/exponent.

Use select_i2c_ch_pca9547() only when CONFIG_FSL_USE_PCA9547_MUX
is set, but several call in board/nxp/lx2160a/lx2160a.c invoke
it unconditionally,
or using unrelated Kconfigs (CONFIG_EMC2305, CONFIG_VID).
Compilation with LX2160A target that omits the mux therefore fails with
error: implicit declaration of function 'select_i2c_ch_pca9547'
Add a static inline stub with -EOPNOTSUPP for the
!CONFIG_FSL_USE_PCA9547_MUX case so all cases compile cleanly.
Adapted from the convention used by include/scmi_nxp_protocols.h for
SCMI subprotocol stubs.
There is no functional change for NXP boards: all eight upstream
LX2160A defconfigs (lx2160ardb / lx2160aqds / lx2162aqds and their
secure / stmm / verified_boot variants) already set
CONFIG_FSL_USE_PCA9547_MUX=y, so the real declaration wins.
The purpose is to support new boards that do not use the PCA9547.

Switch PFUZE100 object linkage to be phase-aware and fix build issues
when using driver model PMIC support.
The PFUZE100 helper code is reworked to:
- Build pfuze.o only when CONFIG_(SPL_)DM_PMIC_PFUZE100 is enabled
- Use CONFIG_IS_ENABLED(DM_PMIC_PFUZE100) for proper DM/non-DM selection
- Align function signatures and implementations with DM PMIC APIs
- Use udevice-based pmic access for DM and legacy pmic for non-DM
- Avoid mixing struct pmic and struct udevice in the same build
configuration
No functional change intended beyond fixing DM support and build
consistency.

There is no user of gd, drop the usage of DECLARE_GLOBAL_DATA_PTR and
the including of "asm/global_data.h". Include config.h to avoid
build error.

This patch renames the board directory from board/freescale to
board/nxp because NXP now provides Board Support Packages (BSPs) and
tools for the former Freescale i.MX and other i.MX products.
All relevant references have been updated accordingly. This change does
not affect functionality.
