hal_nxp: Factorise inclusion of fsl_inputmux

VitekST · cfriedt · commit e679ef486aed · 2025-07-31T17:11:54.000-04:00
Create Kconfig variable NXP_INPUTMUX, which selects the fsl_inputmux
driver. Imply the MCUX component symbol from it. Imply that variable
from the NXP PINT, SmartDMA and LPC DMA drivers and from the mimxrt685s
SoC.

This needed to be done for the mimxrt700_evk/mimxrt798s/hifi4 domain, as
the INPUTMUX peripheral handles IRQ assginments and its driver
(fsl_inputmux) is used directly by the domain's soc.c. Instantiating the
currently dependent drivers (for PINT and SmartDMA) isn's possible nor
reasonable on the said target.
