Tegra114: pinmux: Update pinmux tables & code, fix a bug w/SDMMC3 init

Use the latest tables & code from our internal U-Boot repo.
The SDMMC3_CD, CLK_LB_IN and CLK_LB_OUT offsets in the pingroup
table were off by a few indices, causing the pinmux init code to
write bad data to the PINMUX_AUX_ regs. This also enabled the lock
bit, which made it impossible to reconfig the pads correctly for
SDMMC3 (SD card on Dalmore) operation. Also fixes SPI_CS2_N,
USB_VBUS_EN0, HDMI_CEC and UART2_RXD/TXD muxes.
