[U-Boot] [PATCH] am335x-evm config: decrease bootdelay to 1s and mount rootfs RO

[Koen Kooi]

A fast boot is important to the beaglebone, so save 2 seconds here by
decreasing bootdelay. This is still plenty time to break into the prompt,
I do that at least once a day.

Mount the rootfs RO by default, this is needed to make fsck succeed
without resorting to an initramfs.
