spi: cs42l43: Don't limit native CS to the first chip select
[ Upstream commit 177cddaa5bdfcbc4c3d4594bb44ed8338765fc29 ]
As the chip selects can be configured through ACPI/OF/swnode, and
the set_cs() callback will only be called when a native chip select
is being used, there is no reason for the driver to only support the
native chip select as the first chip select. Remove the check that
introduces this limitation.
