[U-Boot] ARM/ATMEL/AT91: rework SoCs 9261/9263 and others

Dear Friends,

I have received several different patches reworking

"at91sam*_devices.c"

and

"at91sam9*.h".

Lokking at them, none of them is completely done the way the files for at91sam9260 are done.

Examples:

9260, 9263: ATMEL_ID_USART0 9261: ATMEL_ID_US0

9260 uses the CONFIG_AT91_GPIO_PULLUP define, the others do not.

9261 still uses the CONFIG_USARTx defines.

Please have a look at at91sam9260 as a reference.

We do need a properly fixed SoC port for 9261, 9263 and the others before individual board ports can be fixed.

Just because there is a sudden rush to get things fixed for the next release should NOT tempt us to get in interim versions.

With Best Regards, Reinhard
