From: Alberto Panizzo <alberto@xxxxxxxxxxxxxxxxxxxx>
clk_i2sout can be used as codec mclk.
On simple audio card clk_i2sout is just enabled/disabled while the rate
is decided on parent clock by i2s driver.
Without setting CLK_GET_RATE_NOCACHE flag, the get_rate function on
clk_i2sout would return incorrect values after clk_i2sout's parents
update.
