This commit adds support for the B&R brsmarc1 SoM.
The SoM is based on TI's AM335x SoC.
Mainly vxWorks 6.9.4.x is running on the board,
doing some PLC stuff on various carrier boards.

Is there any particular reason for not using the existing pinctrl driver
to do all this pin configuration?
Many thanks for your input.
Not really a (known) reason why not using this driver.
Maybe i just wasn't aware of it. Started in 2013 with first am335x board,
and the style about pinmux setup wasn't changed over time .
Only reason for not changing this NOW is, that i have this boards
already in production and passed internal testing.
But i will look into the pinctrl driver, then convert the board and
bring in that changes within next (internal) release.
After that i will provide some patch for changing that on all BuR am335x
boards (brxre1, brppt1, brsmarc1).
regards Felix
