[PATCH] clk: qcom: Fix a possible NULL pointer dereferencing

[Vivek Gautam <vivek.gautam@codeaurora.org>]

Assign num_parents as 0 while registering fixed rate clocks
in _qcom_cc_register_board_clk(), to make sure the clk framework
doesn't dereference parent.

Fixes: ee15faffef11 ("clk: qcom: common: Add API to register board clocks backwards compatibly")

Based on 'clk-next'. Build tested.
