board/t1024qds: update pin multiplexing
Add multiplexing support among SPI flash, TDM riser card and SDXC.
it routes SPI pins to SPI flash by default.
Route SPI pins to SD slot if "adaptor=sdxc" is set in hwconfig.
Route SPI pins to TDM riser card and do fixup for dts if "pin_mux=tdm"
is set in hwconfig.
