Stefan Potyra 0d7412ed1f spi/bcm63xx-hspi: Enable the clock before calling clk_get_rate(). ...

Enable the clock prior to calling clk_get_rate(), because clk_get_rate()
should only be called if the clock is enabled.

Additionally, prepare/enable the pll_clk before calling clk_get_rate()
for the same reason.
