[PATCH] fixup! pblimage: pblimage: Add LS1028a support

[Ahmad Fatoum]

soc_index is not only used for comparisons, but also as index into the
socs[] array. However, the array starts with SOC_TYPE_LS1046A and the
enum with SOC_TYPE_INVALID leading to socs[SOC_TYPE_LS1046A].soc
== SOC_TYPE_LS1028A and socs[SOC_TYPE_LS1028A] to overflow the array.

This broke LS1046A boot and LS1028A seems to have only worked by chance,
because the memory after socs[] happened to be zeroed.

Fix this by reordering the enum and while at it remove the redundancy in
having both the index and the soc member be the same value.
