Booting OMAP4460 Pandaboard ES with a recent u-boot results in this
warning:

WARNING: at arch/arm/mach-omap2/dpll3xxx.c:427 omap3_noncore_dpll_enable+0xf4/0x110()

The OMAP4 DPLL parent clock names only listed the reference clocks,
not the bypass clocks.  Fix by adding the bypass clocks to the DPLL
parent lists.
