initial builds of OSK5912 boards need srst_pulls_trst
This is clearly noted in the hardware spec (section 5.2.3); it
works around a chip erratum: "If the MPU_RESET signal is used,
it may cause the EMIFS bus to lock."
I seem to have a board with such an initial build. The chip
is labeled XOMAP. Presumably, parts without that "X" prefix
(eXperimental) resolve this.
