pinctrl: samsung: Annotate struct exynos_muxed_weint_data with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct
exynos_muxed_weint_data. Additionally, since the element count member
must be set before accessing the annotated flexible array member, move
its initialization earlier.
