[PATCH v2 1/2] alpha: parse early parameters before reserving contiguous memory

[Magnus Lindholm <linmag7@gmail.com>]

Run parse_early_param() in setup_arch(), after machine initialization
and before further memory reservations. This lets the subsequent CMA
reservation honor cma= before start_kernel() reaches its normal call.

The parser uses boot_command_line and guards against repeated calls.
This moves all early parameter handlers, not just the CMA handler.
