In chapter 'Advisory 2.1 USB Host Clock Drift Causes USB Spec Non-compliance in Certain Configurations' of the TI Errata it is recommended to use certain div/mult values for the DPLL5 clock setup. So far u-boot used the old 34xx values, so I added the errata recommended values specificly for 36xx init only. Also, the FSEL registers exist no longer, so removed them from init.

With this patch, kernel panics disappear and USB working fine in u-boot and kernel.

ARM: omap3: Implement dpll5 (HSUSB clk) workaround for OMAP36xx/AM/DM37xx according to errata sprz318e.

In chapter 'Advisory 2.1 USB Host Clock Drift Causes USB Spec Non-compliance in Certain Configurations' of the TI Errata it is recommended to use certain div/mult values for the DPLL5 clock setup.
So far u-boot used the old 34xx values, so I added the errata recommended values specificly for 36xx init only.
Also, the FSEL registers exist no longer, so removed them from init.

Tested this on a AM3703 board with 19.2MHz oscillator, which previously couldnt lock the dpll5 (kernel complained). As a consequence the EHCI USB port wasnt usable in U-Boot and kernel. With this patch, kernel panics disappear and USB working fine in u-boot and kernel.

ARM: OMAP2+: Rename asm/arch/clocks.h asm/arch/clock.h

To be consistent with other ARM platforms,
renaming asm/arch-omap*/clocks.h to asm/arch-omap*/clock.h
