[PATCH 1/1] efi: Use struct efi_gop_mode_info in struct efi_entry_gopmode

[Heinrich Schuchardt]

Since C99 flexible array members are allowed at the end of structures.
We require C11.

Use struct efi_gop_mode_info in the definition of struct efi_entry_gopmode
to avoid code duplication and unnecessary conversions.
