arm: vf610: Add IOMUX support for Vybrid VF610
This patch adds the IOMUX support for Vybrid VF610 platform.
There is a little difference for IOMUXC module between VF610 and i.MX
platform, the muxmode and pad configuration share one 32bit register on
VF610, but they are two independent registers on I.MX platform. A
CONFIG_IOMUX_SHARE_CONFIG_REG was introduced to fit this difference.
