reset: starfive: jh71x0: Fix accessing the empty member on JH7110 SoC 



data->asserted will be NULL on JH7110 SoC since commit 82327b12
("reset: starfive: Add StarFive JH7110 reset driver") was added. Add
the judgment condition to avoid errors when calling reset_control_status
on JH7110 SoC.

Fixes: 82327b12 ("reset: starfive: Add StarFive JH7110 reset driver")
