Commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various

driver for Poplar platform, because the platform falls into the
following strategy category made by the commit.

  Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

Before the commit lands, Poplar platform works by statically declaring
pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set
in the driver.  But since Poplar also supports device configuration from
device tree, the commit practically drops the flag for Poplar, and hence
breaks the platform from booting.

This patch changes platform code and device tree to initiate pl011
serial device from device tree rather than static declaration, so that
above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore
the reported boot failure gets fixed.

tools: add a generic config for native tools building

The motivation for this is to allow distributions to distribute all
possible tools in a generic way, avoiding the need of specific tools
building for each machine.

Especially on OpenEmbedded / Yocto Project ecosystem, it is very
common each BSP to end providing their specific tools when they need
to generate images for some SoC (e.g MX23 / MX28 in meta-freescale
case).

Using this, we can package the tools doing:
