[PATCH v2] ARM: at91: fix Kconfig.debug by adding DEBUG_AT91_UART option

[Nicolas Ferre]

The DEBUG_AT91_UART Kconfig option was forgotten when moving the
AT91 debug-macro.S file. Add it and use it for the at91.S compilation.

Hi Olof,

This is the second revision of my patch and it must implement your advices
described in your previous email. I'm building a pull-request with it as well
so if you agree, you can take it easily.

Thanks for your help, bye.
