OPP: Fix -Wunsequenced in _of_add_opp_table_v1()
Clang warns (or errors with CONFIG_WERROR=y):
drivers/opp/of.c:1081:28: error: multiple unsequenced modifications to 'val' [-Werror,-Wunsequenced]
1081 | .freq = be32_to_cpup(val++) * 1000,
| ^
1082 | .u_volt = be32_to_cpup(val++),
| ~~
1 error generated.
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.
Fixes: 75bbc92c09d8 ("OPP: Add dev_pm_opp_add_dynamic() to allow more flexibility")
