arm64: dts: ti: k3-j721e-common-proc-board: Add OSPI/Hyperflash select pinmux

J721E common processor board has an onboard mux for selecting whether
the OSPI signals are externally routed to OSPI flash or Hyperflash. The
mux state signal input is tied to WKUP_GPIO0_8 and is used by bootloader
for enabling the corresponding node accordingly. Add pinmux for the same.
