ARM: dts: logicpd-som-lv: Fix wrong pinmuxing on OMAP35

[ Upstream commit 46ff3df87215ff42c0cd2c4bdb7d74540384a69c ]

The pinout of the OMAP35 and DM37 variants of the SOM-LV are the
same, but the macros which define the pinmuxing are different
between OMAP3530 and DM3730.  The pinmuxing was correct for
for the DM3730, but wrong for the OMAP3530.  Since the boot loader
was correctly pin-muxing the pins, this was not obvious. As the
bootloader not guaranteed to pinmux all the pins any more, this
causes an issue, so the pinmux needs to be moved from a common
file to their respective board files.
