[PATCH] drm/amd/pm: Replace 1-element arrays with flexible array members

[Samuel Holland]

Since commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3"),
UBSAN_BOUNDS no longer pretends 1-element arrays are unbounded. The
bounds check is tripped in smu7_get_pp_table_entry_callback_func_v1(),
while reading from mclk_dep_table.

For consistency, fix all affected struct definitions in this file.
