[v2,Precise,SRU] UBUNTU: config: compile the rtc-pl031 driver as static on the highbank kernel flavour

From: Dann Frazier <dann.frazier@canonical.com>

Changes since v1:
    - Updated changelog entry with specifics on failure case
    - Ensured patch formatted against current precise master-next 

The rtc-pl031 driver is used for the RTC on the highbank
platform. Presently it is built as a module in Precise and
Quantal, making the driver unavailable in early boot, yielding
the following error on both releases:

./drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

This behaviour prevents the ability to accurately check the
last-mounted time on the root filesystem.

Ack, looking at configs, the main/platform RTC driver is builtin on
supported platforms. Perhaps we should have something on the enforcer
(rtc-cmos enforced on x86, this on highbank, RTC_DRV_TWL4030 on
armel/omap?)

Also, as already noted, because of the config shuffle modules.ignore
or ignore.modules is needed to be added.

Applied to precise master-next with minor changelog cleanup/tweaks. Also
added modules.ignore for armhf.
