Subject: [PATCH v2] ARM: dts: add core2 padconf region for am3517

According to the technical reference manual for AM35xx system
controller module (SCM) PADCONFS core registers are divided in two
regions: 0x48002030..0x48002268 and 0x480025D8..0x480025FC.
First region is the same for all omap3 SoC and is described in
omap3.dtsi.
The second region is the same as in omap34xx and omap35xx.
The patch adds missing description for the second region.
This patch was tested on AM3517.

 move omap3_pmx_core2 under l4_core -> scm
