i.MX6: mx6q_sabrelite: add CONFIG_REVISION_TAG

This is needed to support Freescale-supplied userspaces.

At the moment, both the IPU and VPU libraries provided by Freescale
in the "imx-lib" package contain routines which scrape the system
revision from /proc/cpuinfo. In the VPU library, this information is
used to load the proper firmware, allowing a single binary to be used
across various i.MX processors.

mx6: Fix reset cause for Power On Reset case

After booting mx6qsabrelite from POR the following is reported:

CPU:   Freescale i.MX61 family rev1.0 at 792 MHz
Reset cause: unknown reset

This is because both the POR and WDOG bits are set after reset.

Fix this by also checking both bits in the POR case.

Cut down the VDDIO/VDDA regulator stabilization delays to 500 uS. That should be

mx6: Read silicon revision from register

Instead of hardcoding the mx6 silicon revision, read it in run-time.

Also, besides the silicon version print the mx6 variant type: quad,dual/solo
or solo-lite.
