Subject: [PATCH v3] ARM: davinci: da8xx: Fix some redefined symbol warnings

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 board files to use da8xx-cfgchip.h
