at91: introduce commom AT91_BASE_SYS
On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.
On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000
This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space
