ice: fix ICE_AQ_LINK_SPEED_M for 200G

When setting PHY configuration during driver initialization, 200G link
speed is not being advertised even when the PHY is capable. This is
because the get PHY capabilities link speed response is being masked by
ICE_AQ_LINK_SPEED_M, which does not include the 200G link speed bit.

ICE_AQ_LINK_SPEED_200GB is defined as BIT(11), but the mask 0x7FF only
covers bits 0-10. Fix ICE_AQ_LINK_SPEED_M to use GENMASK(11, 0) so
that it covers all defined link speed bits including 200G.
