clk: tegra: do not overallocate memory for bpmp clocks

struct tegra_bpmp::clocks is a pointer to a dynamically allocated array
of pointers to 'struct tegra_bpmp_clk'.

But the size of the allocated area is calculated like it is an array
containing actual 'struct tegra_bpmp_clk' objects - it's not true, there
are just pointers.

analysis tool.
