help does not match config - PLL1 vs. PLL0.

In the TRM's (at least in AM1808/OMAP-L138) this register is
"PLLDIV1", not just "DIV1".

I suppose you are not adding CONFIG_SYS_DA850_PLL0_PLLDIV6 to
Kconfig because there is not a way to handle this relationship?
I think it would be just fine to move CONFIG_SYS_DA850_PLL0_PLLDIV6
to Kconfig and give it the default value 0x8000. I suspect that this
comes from the fact that these clocks are supposed to be "fixed ratio"
but there are other clocks that are also "fixed ratio" that are not
handled this way already (PLL0_SYSCLK2, PLL0_SYSCLK4).
