Add defconfig for Linux on Vybrid (vf610) on the secondary Cortex-
M4 CPU. The use of a XIP image has been tested which needs to be
loaded (e.g. using the custom m4boot loader) to the end of the
available RAM at address 0x8f000000. The Cortex-M4 has a code-alias
which makes sure that the instructions get fetched through the code
bus (alias starts at 0x00800000 => 0x80800000 in system address).
Hence, to get optimal performance, use 0x0f000000 as XIP_PHYS_ADDR.
This address is additionally shifted by the length of the minimal
loader which is inserted by m4boot. Currently, this offset is 0x80.

The standard DRAM base address is configured to 0x8C000000, which
gives the Cortex-M4 48MiB of RAM.

Commit ea08de16 ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.

This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.

Make the DP controller device node a consumer of the DISP1 power domain
to ensure that the PD is turned on when the exynos-dp driver is probed.

The L3 Error handling on OMAP5 for the most part is very similar
to that of OMAP4, and had leveraged common data structures and
register layout definitions so far. Upon closer inspection, there
are a few minor differences causing an incorrect decoding and
reporting of the master NIU upon an error:

  1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies
     11 bits on OMAP5 as against 8 bits on OMAP4, with the master
     NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR
     field.
  2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3
     input sources on OMAP5. The common DEBUGSS source is at a
     different input on each SoC.

Fix the above issues by using a OMAP5-specific compatible property
and using SoC-specific data where there are differences.
