The second Ethernet MAC (eQOS) fuse layout is changed since i.MX93 A1
following other i.MX platforms, for example i.MX8MP.

Order for A0:
MAC1_ADDR[15:0]
MAC1_ADDR[31:16]
MAC1_ADDR[47:32]
MAC2_ADDR[47:32]
MAC2_ADDR[15:0]
MAC2_ADDR[31:16]

Order since A1:
MAC1_ADDR[15:0]
MAC1_ADDR[31:16]
MAC1_ADDR[47:32]
MAC2_ADDR[15:0]
MAC2_ADDR[31:16]
MAC2_ADDR[47:32]
