Subject: [PATCH] ARM: OMAP2+: AM33XX: clock data: fix mcasp entries

6ea74cb ARM: OMAP2+: hwmod: get rid of all omap_clk_get_by_name usage
exposes a bug in the AM33XX clock data for mcasp. After moving to
clk_get() usage, the _init() of all registered hwmods fails on mcasp0
due to incorrect clock data causing clk_get() to fail. This causes all
successive hwmods to fail to _init() leaving them in a bad state.

This patch updates the mcasp clock entries so clk_get() will succeed.
It is tested on BeagleBone and is needed for 3.7-rc1 to fix AM33xx
boot.
