[PATCH] slimbus: core: Remove usage of the deprecated ida_simple_xx() API

[Christophe JAILLET]

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So change this change allows one more
device. Previously address 0xFE was never used.

Fixes: 46a2bb5a7f7e ("slimbus: core: Add slim controllers support")

/!\ Untested /!\

The change of behavior is motivated by the comment in
drivers/slimbus/slimbus.h stating that /* Manager's logical address is set
to 0xFF per spec */, so all other values, including 0xFE should be valid,
IMHO.

So considering this as a bug-fix, I added a Fixes tag.
