Subject: mmc: dw_mmc-k3: Fix out-of-bounds access through DT alias

From: Geert Uytterhoeven <[email protected]>

commit 325501d9360eb42c7c51e6daa0d733844c1e790b upstream.

The hs_timing_cfg[] array is indexed using a value derived from the "mshcN" alias in DT, which may lead to an out-of-bounds access.

Fix this by adding a range check.
