The newly introduced support for SAMA5D4 added access to the
'AT91_ALT_BASE_SYS' register area, but failed to define the
symbols in the case when CONFIG_MMU is disabled.
We really should not hardwire addresses like this any more,
but as a small fixup, this patch just adds the missing
definitions for the nommu case, which gets at91x40_defconfig
and any configuration of sam9 and sama5 with MMU disabled
back to work.
