Implementation of ->set_timeout() is supposed to set 'timeout' field of 'struct
watchdog_device' passed to it. sp805 was rather setting this in a local
variable. Fix it.

Basically, this patch does the following:
1. Move the codes of parsing boot parameters from setup-common.c
   to driver. In this way, code reader can know directly that
   there are boot parameters that can change the timeout.
2. Make boot parameter 'booke_wdt_period' effective.
   currently, when driver is loaded, default timeout is always
   being used in stead of booke_wdt_period.
3. Wrap up the watchdog timeout in device struct and clean up
   unnecessary codes.

All three iop variants we support in Linux (iop32x, iop33x and
iop13xx) seem to have support for the watchdog hardware, but this
driver fails to build for the first two of these because it
uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for
iop13xx.

This clarifies the dependency in Kconfig to avoid randconfig
build errors. It is unlikely that anyone will ever miss support
for this driver on the ancient iop3xx platforms, so we don't
need to bother trying to fix it properly.

------------------------------------------------

And also the watchdog's registers will be 32-bits for some versions,
and though it is 16-bits in IMX2+, Vybird and LS+.

Using the regmap APIs, could be more easy to support different

The possible cause of these restarts is that the timeout

the hardware in time.

Add an explicit delay into the ath79_wdt_enable function

shrink_inactive_list() used to wait 0.1s to avoid congestion when all
the pages that were isolated from the inactive list were dirty but not
under active writeback.  That makes no real sense, and apparently causes
major interactivity issues under some loads since 3.11.

The ostensible reason for it was to wait for kswapd to start writing
pages, but that seems questionable as well, since the congestion wait
code seems to trigger for kswapd itself as well.  Also, the logic behind
delaying anything when we haven't actually started writeback is not
clear - it only delays actually starting that writeback.

We'll still trigger the congestion waiting if

 (a) the process is kswapd, and we hit pages flagged for immediate
     reclaim

 (b) the process is not kswapd, and the zone backing dev writeback is
     actually congested.

This probably needs to be revisited, but as it is this fixes a reported
regression.
