mx31: provide readable WEIM CS accessor

setup_weimcs() and some macros are added to support the setup
for i.MX31 WEIM chip selects. As a compromise between verbosity
and readability an ASCII-art'ish bit comment is used instead of
bitfields.
All i.MX31 boards have been patched to use this approach using a
helper program to verify the changes.

MX31: Disable watchdog during low-power modes

Turn on the watchdog WDZST bit so that watchdog timer does not count during low power modes.

Prior to applying this patch mx31pdk board got watchdog resets because when it booted in the Linux prompt
and there was no activity, the system entered into idle mode while watchdog timer was still active.

Fix this by disabling watchdog timer during idle mode.
