Subject: [PATCH 1/2] clk: thead: Fix clk gate registration to pass flags

Modify the call to devm_clk_hw_register_gate_parent_data() to actually
pass the clk flags from hw.init instead of just 0. This is necessary to
allow individual clk gates to specify their own clk flags.

Fixes: ae81b69fd2b1 ("clk: thead: Add support for T-Head TH1520 AP_SUBSYS clocks")
