mfd: intel-lpss: Release IDA resources

BugLink: https://bugs.launchpad.net/bugs/1863019
[ Upstream commit 02f36911c1b41fcd8779fa0c135aab0554333fa5 ]

ida instances allocate some internal memory for ->free_bitmap
in addition to the base 'struct ida'. Use ida_destroy() to release
that memory at module_exit().
