[PATCH v2 2/6] ASoC: es8316: Get sysclk rate from MCLK clock when not explicitly set

[Hongyang Zhao <hongyang.zhao@thundersoft.com>]

When the sysclk has not been set via set_sysclk(), try to get the clock
rate from the MCLK clock provider. This is useful when the codec's MCLK
is managed by an external clock controller and the machine driver does
not explicitly call set_sysclk().
