spi: nxp-fspi: Propagate fwnode in ACPI case as well

[ Upstream commit 40ad64ac25bb736740f895d99a4aebbda9b80991 ]

Propagate fwnode of the ACPI device to the SPI controller Linux device.
Currently only OF case propagates fwnode to the controller.

While at it, replace several calls to dev_fwnode() with a single one
cached in a local variable, and unify checks for fwnode type by using
is_*_node() APIs.
