Subject: [PATCH] bitfield: add u8 helpers
Git-commit: 37a3862e1238262e9866d5d66e5f5f9069cee3a1
Patch-mainline: v4.19-rc1
References: FATE#326294
There's no reason why we shouldn't pack/unpack bits into/from
u8 values/registers/etc., so add u8 helpers.
Use the ____MAKE_OP() macro directly to avoid having nonsense
le8_encode_bits() and similar functions.
