Add a simple socinfo driver for NXP LPC32xx powered boards, the driver
exports SoC family, machine name and the unique SoC ID to userspace.

The unique SoC ID is read from SCB out, it replaces the current platform
specific functionality, which can be removed after adding this driver.

The System Control Block device tree node is added in the change given
below, but the driver operates without a dependency on it, so it does
not cause any regressions on boards with not updated dtb firmware:
