[PATCH 3/3] clk: bd718xx: Implement basic .match_clkspec

[Marek Vasut <marex@denx.de>]

The new match_clkspec() callback is used to determine whether struct clk_hw
that is currently being registered matches the clock specifier currently in
DT "critical-clock" property, and if so, then the CLK_IS_CRITICAL is added
to these newly registered clock.
