[PATCH v2] Add support for Voipac X53-DMM-668 module

[PATCH v2] Add support for Voipac X53-DMM-668 module

[Rostislav Lisovy]

This patchset adds support for Voipac X53-DMM-668 module equipped
with i.mx53 CPU. More info about the module may be found at:
http://www.voipac.com/#X53-DMM-668

The board specific code enables UART0, NAND flash, Ethernet.

Changes since v1:
  Use gpio_request()
  Use already defined VMX53 MACH_TYPE
  A bit of code refactoring
