ARM: lpc32xx: platform updates for v5.1

Here are the changes for ARM NXP LPC32xx platform files:

* removed a superfluous record to kernel log buffer under OOM condition,
* use kmemdup() helper instead of kmalloc()/memcpy() pair,
* removed platform data of ARM PL180 SD/MMC and ARM PL111 LCD controllers,
  since now both are handled in devicetree files.

There are two users upstream which register external callbacks for
switching the port power on/off and overcurrent protection. Both
users only use two GPIOs for that. Instead of having that functionality
in the board files, move the logic into the OHCI driver - including
the interrupt handler for overcurrent detection.
