VIN data groups may appear on different sets of pins, usually named
"vinX_data_[a|b]". The existing VIN_DATA_PIN_GROUP() does not support
appending the '_a' or '_b' suffix, leading to the definition of group
names not consistent with the ones defined using the SH_PFC_PIN_GROUP()
macro.
Fix this by making the VIN_DATA_PIN_GROUP macro a variadic one,
which accepts an optional 'version' argument.

Some VIN channels support less than 24 lanes. As union vin_data always
consumes space for 24 lanes, this wastes memory.
Hence introduce new smaller unions vin_data12 and vin_data16, to
accommodate VIN channels with only 12 or 16 lanes.
This reduces the static pin controller driver size by 320 bytes for
R-Car V2H, and by 96 bytes for R-Car E2.

It has been reported on an older (4.12) kernel but the current upstream
code doesn't cond_resched in the hot remove code at all and the given
range to remove might be really large. Fix the issue by calling
cond_resched once per memory section.

syzbot is reporting too large memory allocation at bfs_fill_super() [1].
Since file system image is corrupted such that bfs_sb->s_start == 0,
bfs_fill_super() is trying to allocate 8MB of continuous memory. Fix
this by adding a sanity check on bfs_sb->s_start, __GFP_NOWARN and
printf().

We include kexec.h and slab.h twice in kexec_file.c. It's unnecessary.
hence just remove them.
