c-periphery: new package 

This package is needed as a dependency of lua-periphery. Currently,
c-periphery is automatically cloned by lua-periphery, which causes two
problems:

 1/ It does not integrate properly with the download infrastructure of
    Buildroot, making offline builds impossible since not the entire
    source code is downloaded by Buildroot.

 2/ It does not use the latest version of c-periphery, which has some
    fixes contributed by Vicente to fix c-periphery on MIPS.

Introducing this package is needed as part of the fix for the
following build failure:

	  c-periphery is a set of C wrapper functions for GPIO, SPI,

	  I2C, MMIO, and Serial peripheral I/O interface access in

	  userspace Linux. The c-periphery wrappers simplify and

	  consolidate the native Linux APIs to these

	  interfaces. c-periphery is useful in embedded Linux

	  environments (including BeagleBone, Raspberry Pi,

	  etc. platforms) for interfacing with external

	  peripherals. c-periphery is re-entrant, uses static

	  allocations, has no dependencies outside the standard C

	  library and Linux, compiles into a static library for easy

	  integration with other projects, and is MIT licensed.
