ENGR00210014 i.mx6 : i.mx6sl : add PAD_CTL_LVE support for pad configuration
Original pad configuration don't provide enough bitfield width to hold
all necessary information. For MX6Sololite, a "PAD_CTL_LVE" is needed
to be configed for many pins.
iomux_v3_cfg_t is re-orgnized to address this issue. PAD_CTRL is
extended by 1 bit to hold the "PAD_CTL_LVE". Which is mapped to proper
bit location when configure the PAD config register.
