From: Benoit Cousson <b-cousson@xxxxxx>
Fix a few OMAP4430 clock tree problems after the recent manual merge of the
various ES2 clock patches:
- usim optional clock and its parent had the same name, rename the parent
usim_fclk -> usim_ck
- OPTFCLKEN_CLK32K is not handled anymore by the USBPHYOCP2SCP module in ES2
Create a new clock that belongs to CM_ALWON_USBPHY_CLKCTRL register
This patch depends on some of the PRCM macro updates from Rajendra.
