ARM: davinci: da8xx: Fix sleeping function called from invalid context
Everytime the usb20 phy is enabled, there is a "sleeping function called from invalid context" BUG. In addition, there is a recursive locking happening because of the recurse call to clk_enable(). clk_enable() from arch/arm/mach-davinci/clock.c uses spin_lock_irqsave() before to invoke the callback usb20_phy_clk_enable(). usb20_phy_clk_enable() uses clk_get() and clk_enable_prepapre() which may sleep. Replace clk_prepare_enable() by davinci_clk_enable().
