[PATCH v2] Fix some potential warnings

[Alexandre Bailon]

Some changes I'm working on causes some warning because two included
headers defines the same macros.

Change in V2:
Update the d830 evm board file to use the da8xx-cfgchip.h
These changes are required as I'm sending this patch apart from
the series "[PATCH/RFT v2 00/17] Add DT support for ohci-da8xx"

[PATCH v2] ARM: davinci: da8xx: Fix some redefined symbol warnings

[Alexandre Bailon]

Some macro for DA8xx CFGCHIP are defined in usb-davinci.h,
but da8xx-cfgchip.h intend to replace them.
The usb-da8xx.c is using both headers, causing redefined symbol warnings.
Remove the macro and update the da830-evm board file to use da8xx-cfgchip.h

This leads to build error on v4.9-rc2:

arch/arm/mach-davinci/board-da830-evm.c: In function 'da830_evm_usb_init':
arch/arm/mach-davinci/board-da830-evm.c:120:15: error: 'CFGCHIP2_REFFREQ' undeclared (first use in this function)
  cfgchip2 &= ~CFGCHIP2_REFFREQ;

Thanks,
