Subject: [PATCH 1/3] ASoC: ti: omap-mcbsp: Ignore errors for getting fck_src

Commit 349355ce3a05 ("ARM: OMAP2+: Drop legacy platform data for omap4 mcbsp")
dropped prcm_fck for omap4, so the clk_src might not be available making the
clk_get(src) fail. In such cases, rely on the devicetree to assign
the correct parent.
