slimbus: core: Remove usage of the deprecated ida_simple_xx() API
[ Upstream commit 89ffa4cccec54467446f141a79b9e36893079fb8 ]
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.
