Add read_buf/write_buf for s3c2440, which can read/write 32 bits at a
time rather than just 8. In my testing on an s3c2440a running at 400 MHz
with a 100 MHz HCLK, read performance improves by 36% (from 5.19 MB/s
to 7.07 MB/s).

[In commit 9ed437c5 we fixed a problem 
with standard permissions on newly-created inodes, when POSIX ACLs are 
enabled. This cleans it up...]

The attached patch separate jffs2_init_acl() into two parts.

The one is jffs2_init_acl_pre() called from jffs2_new_inode().
It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL
objects associated with the new inode just before when inode meta
infomation is written to the medium.

The other is jffs2_init_acl_post() called from jffs2_symlink(),
jffs2_mkdir(), jffs2_mknod() and jffs2_do_create().
It actually writes in-memory ACL objects into the medium next to
the success of writing meta-information.

In the current implementation, we have to write a same inode meta
infomation twice when inode->i_mode is updated by the default ACL.
However, we can avoid the behavior by putting an updated i_mode
before it is written at first, as jffs2_init_acl_pre() doing.

This reverts commit a5bf3d89.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:

  "That Kconfig hasn't changed (other than adding new drivers), and it's
   worked that way for several years now ...  so the issue seems to be
   changes in menuconfig/kconfig/etc semantics.

   The issue is that when USB_GADGET=m, it's no longer possible to
   configure peripheral controller drivers as modules ...  the
   controller drivers can now only be configured for static linkage.

   It should be making a choice of one of the controller drivers which
   could work on the target system, and allow that driver to be linked
   either as a module (ok iff USB_GADGET=m) or statically."

Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.
