ARM: at91: avoid defining CONFIG_* symbols in source code
In an invalid randconfig build (fixed by another patch),
I ran across this warning:
arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror]
#define CONFIG_DEBUG_UART_VIRT AT91_IO_P2V(CONFIG_DEBUG_UART_PHYS)
As Russell pointed out, we should never #define a macro starting
with CONFIG_ in a source file, as that is rather confusing.
This renames the macro to avoid the symbol clash.
