[PATCH 1/2] config/arm: fix CN10K minimum march requirement

[pbhagavatula]

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Meson selects march and mcpu based on compiler support and
partnumber, only the minimum required march should be defined
in cross compile configuration file.

Fixes: 1b4c86a721c9 ("config/arm: add Marvell CN10K")

The host_machine.cpu in cross file doesn't take effect.
There is an effort to remove the confusion. Can you have a review?
