Subject: MIPS: Fix address type used for early memory detection.

MIPS: Fix address type used for early memory detection.

In 'early_parse_mem' the data type used for the start
and size of a memory region specified on the command line
is incorrect. If 64-bit addressing is used, the value
gets truncated.
