OPP: Fix -Wunsequenced in _of_add_opp_table_v1()

Browse Source 
Clang warns (or errors with CONFIG_WERROR=y):

  drivers/opp/of.c:1081:28: error: multiple unsequenced modifications to 'val' [-Werror,-Wunsequenced]

There is no sequence point in a designated initializer. Move back to
separate variables for the creation of the values, so that there are
sequence points between each evaluation and increment of val.
