board: nxp: common: support CONFIG_FSL_USE_PCA9547_MUX
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.
