[meta-ti] [PATCH v2 4/4] am335x-evm.conf: Add 'ubi' to IMAGE_FSTYPES, use '=' in assignment

[Tom Rini]

As per
http://lists.linuxtogo.org/pipermail/openembedded-core/2012-March/019772.html
a machine conf file should use '=' to set IMAGE_FSTYPES.  We also add
the required MKUBIFS_ARGS / UBINIZE_ARGS.  These are placed next to the
line that sets us to use the PSP kernel tree and reference the TI wiki
for the source of our info as well as dmesg / userland commands.
