Packed structure cfi_qry contains unaligned 16- and 32-bits members,
accessing which causes problems when cfi_flash driver is compiled with
-munaligned-access option: flash initialization hangs, probably
due to data error.
Since fixing the code to use some other way of accessing those fields
seems quite expensive, just force the compiler to use -mno-unaligned-access.
