[PATCH v2 6/6] clk: qcom: apq8016: Fix SDCC clock warnings

[Stephan Gerhold]

As of commit dc8754e8e408 ("clk/qcom: apq8016: improve clk_enable logging")
there are now warnings in the U-Boot console on DragonBoard 410c:

  apq8016_clk_enable: unknown clk id 122
  apq8016_clk_enable: unknown clk id 123
  apq8016_clk_enable: unknown clk id 124
  apq8016_clk_enable: unknown clk id 125

This is because we don't implement enable() properly for the SDCC clocks.
Currently they are being enabled as part of set_rate().

Fix this by moving the enable calls out of the apq8016_clk_init_sdc()
function and convert them to the equivalent GATE_CLK_POLLED() definitions.
