[OE-core] [PATCH] wic/bootimg-efi: allow multiple initrd

[chee.yang.lee at intel.com]

From: Chee Yang Lee <chee.yang.lee at intel.com>

Allow plugin bootimg-efi to configure with multiple initrd
through source parameter.

Uses ; to separate each initrd.

e.g:
--sourceparams="loader=${EFI_PROVIDER},initrd=initrd1;initrd2"
