efikamx: configure Smarttop PCBID and LED pads in DCD for convenience 

PCBID pads seem to need time to settle due to external pulldowns, otherwise
we are reading floating GPIO pins with implicit pad pullups and get the wrong
data. However we can't "wait" at the time we need them before relocation,
since timers are not available. The time taken to get from DCD to the code
requiring the pads set seems to be more than long enough (even with caches
enabled).

We have space in the DCD due to the DDR settings changes to configure all
the pad settings we need for this, plus the LED pad settings too which
reduces the amount of code required later on.
