[PATCH] arm: mach-k3: introduce generic board detction kconfig option

[Christian Gmeiner]

For non TI boards it is not possible to enable the do_board_detect()
call as TI_I2C_BOARD_DETECT is defined in board/ti/common/Kconfig.

I want to use do_board_detect() to dectect boards and properties based
on some SPI communication with a FPGA.
