clk: renesas: Provide Kconfig symbols for CPG/MSSR and CPG/MSTP support

Currently the decision whether to build the renesas-cpg-mssr and
clk-mstp drivers is handled by Makefile logic.  However, the rcar-sysc
driver will need to know whether CPG/MSSR and/or CPG/MSTP support are
available or not.

To avoid having to duplicate this logic, move it to Kconfig. Provide
non-visible CLK_RENESAS_CPG_MSSR and CLK_RENESAS_CPG_MSTP Kconfig
symbols, which can be used by both Makefiles and C code.

Revert "ext4: allow readdir()'s of large empty directories to be interrupted"

This reverts commit 1028b55bafb7611dda1d8fed2aeca16a436b7dff.

It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.

You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.

I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.

So my track record is not good enough, and the stars will have to align
better before that one gets committed.  And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.

IOW, let's just revert the commit that caused the problem for now.

Pull GPIO fixes from Linus Walleij:
 "Here is a set of four GPIO fixes.  The two fixes to the core are
  serious as they are regressing minor architectures.

  Core fixes:

   - Defer GPIO device setup until after gpiolib is initialized.

     It turns out that a few very tightly integrated GPIO platform
     drivers initialize so early (befor core_initcall()) so that the
     gpiolib isn't even initialized itself.  That limits what the
     library can do, and we cannot reference uninitialized fields until
     later.

     Defer some of the initialization until right after the gpiolib is
     initialized in these (rare) cases.

   - As a consequence: do not use devm_* resources when allocating the
     states in the initial set-up of the gpiochip.

  Driver fixes:

   - In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.

   - Fix legacy builds on the PXA without a backing pin controller.

   - Use correct datatype on pca953x register writes"
